About Installing 1
When you install vRealize Operations Manager, you can install the product in an environment that has
never been monitored by vRealize Operations Manager. You can also migrate, which captures an
environment monitored by a previous version of vRealize Operations Manager so that the new copy of
vRealize Operations Manager can monitor that environment.
You can migrate at installation time, or you can postpone a migration until after your copy of
vRealize Operations Manager is in production use. In other words, you can run
vRealize Operations Manager to monitor a fresh environment, and at any time, decide to add an
environment that was being monitored by a previous vRealize Operations Manager.

Installation Overview
You prepare for vRealize Operations Manager installation by evaluating your environment and deploying
enough vRealize Operations Manager cluster nodes to support how you want to use the product.
Workflow of vRealize Operations Manager Installation
The vRealize Operations Manager virtual appliance installation process consists of deploying the
vRealize Operations Manager OVF or an installer once for each cluster node, accessing the product to set up
cluster nodes according to their role, and logging in to congure the installation.
Figure 1‑1. vRealize Operations Manager Installation Architecture
8 VMware, Inc.
Sizing the vRealize Operations Manager Cluster
The resources needed for vRealize Operations Manager depend on how large of an environment you expect
to monitor and analyze, how many metrics you plan to collect, and how long you need to store the data.
It is dicult to broadly predict the CPU, memory, and disk requirements that will meet the needs of a
particular environment. There are many variables, such as the number and type of objects collected, which
includes the number and type of adapters installed, the presence of HA, the duration of data retention, and
the quantity of specic data points of interest, such as symptoms, changes, and so on.
VMware expects vRealize Operations Manager sizing information to evolve, and maintains Knowledge Base
articles so that sizing calculations can be adjusted to adapt to usage data and changes in versions of
vRealize Operations Manager.
Knowledge Base article 2093783
The Knowledge Base articles include overall maximums, plus spreadsheet calculators in which you enter the
number of objects and metrics that you expect to monitor. To obtain the numbers, some users take the
following high-level approach, which uses vRealize Operations Manager itself.
1 Review this guide to understand how to deploy and congure a vRealize Operations Manager node.
2 Deploy a temporary vRealize Operations Manager node.
Chapter 1 About Installing
3 Congure one or more adapters, and allow the temporary node to collect overnight.
4 Access the Cluster Management page on the temporary node.
5 Using the Adapter Instances list in the lower portion of the display as a reference, enter object and
metric totals of the dierent adapter types into the appropriate sizing spreadsheet from Knowledge
Base article 2093783.
6 Deploy the vRealize Operations Manager cluster based on the spreadsheet sizing recommendation. You
can build the cluster by adding resources and data nodes to the temporary node or by starting over.
If you have a large number of adapters, you might need to reset and repeat the process on the temporary
node until you have all the totals you need. The temporary node will not have enough capacity to
simultaneously run every connection from a large enterprise.
Another approach to sizing is through self monitoring. Deploy the cluster based on your best estimate, but
create an alert for when capacity falls below a threshold, one that allows enough time to add nodes or disk
to the cluster. You also have the option to create an email notication when thresholds are passed.
During internal testing, a single-node vApp deployment of vRealize Operations Manager that monitored
8,000 virtual machines ran out of disk storage within one week.
Add Data Disk Space to a vRealize Operations Manager vApp Node
You add to the data disk of vRealize Operations Manager vApp nodes when space for storing the collected
data runs low.
Prerequisites
Note the disk size of the analytics cluster nodes. When adding disk, you must maintain uniform size
n
across analytics cluster nodes.
Use the vRealize Operations Manager administration interface to take the node oine.
n
Verify that you are connected to a vCenter Server system with a vSphere client, and log in to the

About vRealize Operations Manager Cluster Nodes
All vRealize Operations Manager clusters consist of a master node, an optional replica node for high
availability, optional data nodes, and optional remote collector nodes.
When you install vRealize Operations Manager, you use a vRealize Operations Manager vApp deployment
to create role-less nodes. After the nodes are created and have their names and IP addresses, you use an
administration interface to congure them according to their role.
You can create role-less nodes all at once or as needed. A common as-needed practice might be to add nodes
to scale out vRealize Operations Manager to monitor an environment as the environment grows larger.
12 VMware, Inc.
The following node types make up the vRealize Operations Manager analytics cluster:
Chapter 1 About Installing
Master Node
Data Node
Replica Node
The following node type is a member of the vRealize Operations Manager cluster but not part of the
analytics cluster:
Remote Collector Node
The initial, required node in vRealize Operations Manager. All other nodes
are managed by the master node.
In a single-node installation, the master node manages itself, has adapters
installed on it, and performs all data collection and analysis.
In larger deployments, additional data nodes have adapters installed and
perform collection and analysis.
Larger deployments usually include adapters only on the data nodes so that
master and replica node resources can be dedicated to cluster management.
To use vRealize Operations Manager high availability (HA), the cluster
requires that you convert a data node into a replica of the master node.
Distributed deployments might require a remote collector node that can
navigate rewalls, interface with a remote data source, reduce bandwidth
across data centers, or reduce the load on the vRealize Operations Manager
analytics cluster. Remote collectors only gather objects for the inventory,
without storing data or performing analysis. In addition, remote collector
nodes may be installed on a dierent operating system than the rest of the
cluster.
About vRealize Operations Manager Remote Collector Nodes
A remote collector node is an additional cluster node that allows vRealize Operations Manager to gather
more objects into its inventory for monitoring. Unlike data nodes, remote collector nodes only include the
collector role of vRealize Operations Manager, without storing data or processing any analytics functions.
A remote collector node is usually deployed to navigate rewalls, reduce bandwidth across data centers,
connect to remote data sources, or reduce the load on the vRealize Operations Manager analytics cluster.
Remote collectors do not buer data while the network is experiencing a problem. If the connection between
remote collector and analytics cluster is lost, the remote collector does not store data points that occur
during that time. In turn, and after the connection is restored, vRealize Operations Manager does not
retroactively incorporate associated events from that time into any monitoring or analysis.
You must have at least a master node before adding remote collector nodes.
About vRealize Operations Manager High Availability
vRealize Operations Manager supports high availability (HA). HA creates a replica for the
vRealize Operations Manager master node and protects the analytics cluster against the loss of a node.
With HA, data stored on the master node is always 100% backed up on the replica node. To enable HA, you
must have at least one data node deployed, in addition to the master node.
HA is not a disaster recovery mechanism. HA protects the analytics cluster against the loss of only one
n
node, and because only one loss is supported, you cannot stretch nodes across vSphere clusters in an
aempt to isolate nodes or build failure zones.
When HA is enabled, the replica can take over all functions that the master provides, were the master to
n
fail for any reason. If the master fails, failover to the replica is automatic and requires only two to three
minutes of vRealize Operations Manager downtime to resume operations and restart data collection.
VMware, Inc. 13
vRealize Operations Manager vApp Deployment and Configuration Guide
When a master node problem causes failover, the replica node becomes the master node, and the cluster
runs in degraded mode. To get out of degraded mode, take one of the following steps.
Return to HA mode by correcting the problem with the master node. When a master node exits an
n
HA-enabled cluster, master node does not rejoin with the cluster without manual intervention.
Therefore, restart the vRealize Operations Analytics process on the downed node to change its role
to replica and rejoin the cluster.
Return to HA mode by converting a data node into a new replica node and then removing the old,
n
failed master node. Removed master nodes cannot be repaired and re-added to
vRealize Operations Manager.
Change to non-HA operation by disabling HA and then removing the old, failed master node.
n
Removed master nodes cannot be repaired and re-added to vRealize Operations Manager.
In the administration interface, after an HA replica node takes over and becomes the new master node,
n
you cannot remove the previous, oine master node from the cluster. In addition, the previous node
continues to be listed as a master node. To refresh the display and enable removal of the node, refresh
the browser.
When HA is enabled, the cluster can survive the loss of one data node without losing any data.
n
However, HA protects against the loss of only one node at a time, of any kind, so simultaneously losing
data and master/replica nodes, or two or more data nodes, is not supported. Instead,
vRealize Operations Manager HA provides additional application level data protection to ensure
application level availability.
When HA is enabled, it lowers vRealize Operations Manager capacity and processing by half, because
n
HA creates a redundant copy of data throughout the cluster, as well as the replica backup of the master
node. Consider your potential use of HA when planning the number and size of your
vRealize Operations Manager cluster nodes. See “Sizing the vRealize Operations Manager Cluster,” on
page 9.
When HA is enabled, deploy analytics cluster nodes on separate hosts for redundancy and isolation.
n
One option is to use anti-anity rules that keep nodes on specic hosts in the vSphere cluster.
If you cannot keep the nodes separate, you should not enable HA. A host fault would cause the loss of
more than one node, which is not supported, and all of vRealize Operations Manager would become
unavailable.
The opposite is also true. Without HA, you could keep nodes on the same host, and it would not make a
dierence. Without HA, the loss of even one node would make all of vRealize Operations Manager
unavailable.
When you power o the data node and change the network seings of the VM, this aects the IP
n
address of the data node. After this point, the HA cluster is no longer accessible and all the nodes have
a status of "Waiting for analytics". Verify that you have used a static IP address.
When you remove a node that has one or more vCenter adapters congured to collect data from a HA-
n
enabled cluster, one or more vCenter adapters associated with that node stops collecting. You change
the adapter conguration to pin them to another node before removing the node.
Administration UI shows the resource cache count, which is created for active objects only, but the
n
Inventory Explorer displays all objects. Therefore, when you remove a node from a HA-enabled cluster
allowing the vCenter adapters collect data and rebalance each node, the Inventory explorer displays a
dierent quantity of objects from that shown in the Administration UI.

Preparing for Installation 2
You preparing for your installation, consider some of these best practises, platform, and cluster
requirements.
This chapter includes the following topics:
“Platform requirements for vRealize Operations Manager,” on page 15
n
“Requirements,” on page 15
n
Platform requirements for vRealize Operations Manager
vRealize Operations Manager requires the following hardware and software when you install on any
platform.
Requirements
You have to consider important requirements while creating nodes in a vRealize Operations Manager.
Using IPv6 with vRealize Operations Manager
vRealize Operations Manager supports Internet Protocol version 6 (IPv6), the network addressing
convention that will eventually replace IPv4. Use of IPv6 with vRealize Operations Manager requires that
certain limitations be observed.
VMware, Inc.
Using IPv6
All vRealize Operations Manager cluster nodes, including remote collectors, must have IPv6 addresses.
n
Do not mix IPv6 and IPv4.
All vRealize Operations Manager cluster nodes, including remote collectors, must be vApp based.
n
Use global IPv6 addresses only. Link-local addresses are not supported.
n
If any nodes use DHCP, your DHCP server must be congured to support IPv6.
n
DHCP is only supported on data nodes and remote collectors. Master nodes and replica nodes still
n
require xed addresses, which is true for IPv4 as well.
Your DNS server must be congured to support IPv6.
n
When adding nodes to the cluster, remember to enter the IPv6 address of the master node.
n
When registering a VMware vCenter® instance within vRealize Operations Manager, place square
n
brackets around the IPv6 address of your VMware vCenter Server® system if vCenter is also using IPv6.
For example: [2015:0db8:85a3:0042:1000:8a2e:0360:7334]
15
vRealize Operations Manager vApp Deployment and Configuration Guide
Note that, even when vRealize Operations Manager is using IPv6, vCenter Server may still have an IPv4
address. In that case, vRealize Operations Manager does not need the square brackets.
Cluster Requirements
When you create the cluster nodes that make up vRealize Operations Manager, you have general
requirements that you must meet.
General vRealize Operations Manager Cluster Node Requirements
You have to follow some general requirements to create a node on your environment.
General Requirements
vRealize Operations Manager version. All nodes must run the same vRealize Operations Manager
n
version.
For example, do not add a version 6.1 data node to a cluster of vRealize Operations Manager 6.2 nodes.
Analytics Cluster Deployment Type. In the analytics cluster, all nodes must be the same kind of
n
deployment: vApp.
Remote Collector Deployment Type. A remote collector node does not need to be the same deployment
n
type as the analytics cluster nodes.
When you add a remote collector of a dierent deployment type, the following clusters are supported:
vApp analytics cluster
n
Analytics Cluster Node Sizing. In the analytics cluster, CPU, memory, and disk size must be identical
n
for all nodes.
Master, replica, and data nodes must be uniform in sizing.
Remote Collector Node Sizing. Remote collector nodes may be of dierent sizes from each other or
n
from the uniform analytics cluster node size.
Geographical Proximity. You may place analytics cluster nodes in dierent vSphere clusters, but the
n
nodes must reside in the same geographical location.
Dierent geographical locations are not supported.
Virtual Machine Maintenance. When any node is a virtual machine, you may only update the virtual
n
machine software by directly updating the vRealize Operations Manager software.
For example, going outside of vRealize Operations Manager to access vSphere to update VMware Tools
is not supported.
Redundancy and Isolation. If you expect to enable HA, place analytics cluster nodes on separate hosts.
n
See “About vRealize Operations Manager High Availability,” on page 13.
You can deploy remote collectors behind a rewall. You cannot use NAT between remote collectors and
n
analytics nodes.
Requirements for Solutions
Be aware that solutions might have requirements beyond those for vRealize Operations Manager itself. For
example, vRealize Operations Manager for Horizon View has specic sizing guidelines for its remote
collectors.
See your solution documentation, and verify any additional requirements before installing solutions. Note
that the terms solution, management pack, adapter, and plug-in are used somewhat interchangeably.
16 VMware, Inc.
Chapter 2 Preparing for Installation
vRealize Operations Manager Cluster Node Networking Requirements
When you create the cluster nodes that make up vRealize Operations Manager, the associated setup within
your network environment is critical to inter-node communication and proper operation.
Networking Requirements
I vRealize Operations Manager analytics cluster nodes need frequent communication with one
another. In general, your underlying vSphere architecture might create conditions where some vSphere
actions aect that communication. Examples include, but are not limited to, vMotions, storage vMotions,
HA events, and DRS events.
The master and replica nodes must be use static IP address, or fully qualied domain name (FQDN)
n
with a static IP address.
Data and remote collector nodes can use dynamic host control protocol (DHCP).
You can successfully reverse-DNS all nodes, including remote collectors, to their FQDN, currently the
n
node hostname.
Nodes deployed by OVF have their hostnames set to the retrieved FQDN by default.
All nodes, including remote collectors, must be bidirectionally routable by IP address or FQDN.
n
Do not separate analytics cluster nodes with network address translation (NAT), load balancer, rewall,
n
or a proxy that inhibits bidirectional communication by IP address or FQDN
Analytics cluster nodes must not have the same hostname.
n
Place analytics cluster nodes within the same data center and connect them to the same local area
n
network (LAN).
Place analytics cluster nodes on same Layer 2 network and IP subnet.
n
A stretched Layer 2 or routed Layer 3 network is not supported.
Do not span the Layer 2 network across sites, which might create network partitions or network
n
performance issues.
One-way latency between the analytics cluster nodes must be 5 ms or lower.
n
Network bandwidth between the analytics cluster nodes must be one gbps or higher.
n
Do not distribute analytics cluster nodes over a wide area network (WAN).
n
To collect data from a WAN, a remote or separate data center, or a dierent geographic location, use
remote collectors.
Remote collectors are supported through a routed network but not through NAT.
n
Do not include an underscore in the hostname of any cluster node.
n
vRealize Operations Manager Cluster Node Best Practices
When you create the cluster nodes that make up vRealize Operations Manager, additional best practices
improve performance and reliability in vRealize Operations Manager.
Best Practices
Deploy vRealize Operations Manager analytics cluster nodes in the same vSphere cluster in a single
n
datacenter and add only one node at a time to a cluster allowing it to complete before adding another
node.
VMware, Inc. 17
vRealize Operations Manager vApp Deployment and Configuration Guide
If you deploy analytics cluster nodes in a highly consolidated vSphere cluster, you might need resource
n
reservations for optimal performance.
Determine whether the virtual to physical CPU ratio is aecting performance by reviewing CPU ready
time and co-stop.
Deploy analytics cluster nodes on the same type of storage tier.
n
To continue to meet analytics cluster node size and performance requirements, apply storage DRS anti-
n
anity rules so that nodes are on separate datastores.
To prevent unintentional migration of nodes, set storage DRS to manual.
n
To ensure balanced performance from analytics cluster nodes, use ESXi hosts with the same processor
n
frequencies. Mixed frequencies and physical core counts might aect analytics cluster performance.
To avoid a performance decrease, vRealize Operations Manager analytics cluster nodes need
n
guaranteed resources when running at scale. The vRealize Operations Manager Knowledge Base
includes sizing spreadsheets that calculate resources based on the number of objects and metrics that
you expect to monitor, use of HA, and so on. When sizing, it is beer to over-allocate than underallocate resources.
See Knowledge Base article 2093783.
Because nodes might change roles, avoid machine names such as Master, Data, Replica, and so on.
n
Examples of changed roles might include making a data node into a replica for HA, or having a replica
take over the master node role.
The NUMA placement is removed in the vRealize Operations Manager 6.3 and later. Procedures related

About the vRealize Operations Manager Master Node
The master node is the required, initial node in your vRealize Operations Manager cluster.
The master node performs administration for the cluster and must be online before you congure any new
nodes. In addition, the master node must be online before other nodes are brought online. If the master node
and replica node go oine together, bring them back online separately. Bring the master node completely
online rst, and then bring the replica node online. For example, if the entire cluster were oine for any
reason, you would bring the master node online rst.
Advantages of a New installation
You can use the new installation to create a new master node during the rst installation of
vRealize Operations Manager. With the master node in place, you can then start adding more nodes to form
a cluster and then dene an environment for your organization.
In a single-node clusters, administration and data are on the same master node. A multiple-node cluster
includes one master node and one or more data nodes. In addition, there might be remote collector nodes,
and there might be one replica node used for high availability. For more information on creating a master
node, see “About the vRealize Operations Manager Master Node,” on page 23.

Installing vRealize Operations Manager as an Administrator
As an administrator, you can install several instances of vRealize Operations Manager build in your VM
environment.
Introduction to Express Installation
Express installation is one possible way to create master nodes, add data nodes, form clusters and test your
connection status. You can use express installation to save time and speed up the process of installation
when compared to new installation. It is recommended not to use this feature unless the user is an
administrator.

24 VMware, Inc.
Chapter 3 Installing vRealize Operations Manager
Advantages of an Express Installation
Express installation saves time when compared to a new installation to create a new master node. The
express installation uses the default certicates, which diers from one organization to another. This feature
is mainly used by the developers or the administrators.
Expand an Existing Installation of vRealize Operations Manager
Use this option to add a node to an existing vRealize Operations Manager cluster. You can use this option if
you have already congured a master node and you want to increase the capacity by adding more nodes to
your cluster.
Introduction to Expand an Existing Installation
You can deploy and congure additional nodes so that vRealize Operations Manager can support larger
environments. A master node always requires an additional node for a cluster to monitor your environment.
With expanding your installation, you can add more than one node to your cluster.
Adding Data Nodes
Data nodes are the additional cluster nodes that allow you to scale out vRealize Operations Manager to
monitor larger environments.
You can dynamically scale out vRealize Operations Manager by adding data nodes without stopping the
vRealize Operations Manager cluster. When you scale out the cluster by 25% or more, you should restart the
cluster to allow vRealize Operations Manager to update its storage size, and you might notice a decrease in
performance until you restart. A maintenance interval provides a good opportunity to restart the
vRealize Operations Manager cluster.
In addition, the product administration options include an option to re-balance the cluster, which can be
done without restarting. Rebalancing adjusts the vRealize Operations Manager workload across the cluster
nodes.
Figure 3‑4. Expand an existing installation from the Setup screen
N Do not shut down online cluster nodes externally or by using any means other than the
vRealize Operations Manager interface. Shut down a node externally only after taking it oine in the
vRealize Operations Manager interface.
Expand an Existing Installation to Add a Data Node

vRealize Operations Manager master node.
Run the Setup Wizard to Add a Master Replica Node
You can convert a vRealize Operations Manager data node to a replica of the master node, which adds high
availability (HA) for vRealize Operations Manager.
N If the cluster is running, enabling HA restarts the cluster.
If you convert a data node that is already in use for data collection and analysis, adapters and data
connections that were provided through that data node fail over to other data nodes.
You may add HA to the vRealize Operations Manager cluster at installation time or after
vRealize Operations Manager is up and running. Adding HA at installation is less intrusive because the
cluster has not yet started.

About Logging In to vRealize Operations Manager
Logging in to vRealize Operations Manager requires that you point a Web browser to the fully qualied
domain name (FQDN) or IP address of a node in the vRealize Operations Manager cluster.
When you log in to vRealize Operations Manager, there are a few things to keep in mind.
After initial conguration, the product interface URL is:
n
hps://node-FQDN-or-IP-address
Before initial conguration, the product URL opens the administration interface instead.
n
After initial conguration, the administration interface URL is:
n
hps://node-FQDN-or-IP-address/admin
The administrator account name is admin. The account name cannot be changed.
n
The admin account is dierent from the root account used to log in to the console, and does not need to
n
have the same password.
When logged in to the administration interface, avoid taking the node that you are logged into oine
n
and shuing it down. Otherwise, the interface closes.
The number of simultaneous login sessions before a performance decrease depends on factors such as
n
the number of nodes in the analytics cluster, the size of those nodes, and the load that each user session
expects to put on the system. Heavy users might engage in signicant administrative activity, multiple
simultaneous dashboards, cluster management tasks, and so on. Light users are more common and
often require only one or two dashboards.
The sizing spreadsheet for your version of vRealize Operations Manager contains further detail about
simultaneous login support. See Knowledge Base article 2093783.

of data that you want.
Log In and Continue with a New Installation
To nish a new vRealize Operations Manager installation, you log in and complete a one-time process to
license the product and congure solutions for the kinds of objects that you want to monitor.
Prerequisites
Create the new cluster of vRealize Operations Manager nodes.
n
Verify that the cluster has enough capacity to monitor your environment. See “Sizing the vRealize
n
Operations Manager Cluster,” on page 9.
Procedure
1 In a Web browser, navigate to the IP address or fully qualied domain name of the master node.
2 Enter the username admin and the password that you dened when you congured the master node,
and click Login.
Because this is the rst time you are logging in, the administration interface appears.
3 To start the cluster, click Start vRealize Operations Manager.
4 Click Yes.
The cluster might take from 10 to 30 minutes to start, depending on your environment. Do not make
changes or perform any actions on cluster nodes while the cluster is starting.

Updating, Migrating and Restoring 6
You can update your existing vRealize Operations Manager deployments to a newly released version.
When you perform a software update, you need to make sure you use the correct PAK le for your cluster. A
good practice is to take a snapshot of the cluster before you update the software, but you must remember to
delete the snapshot once the update is complete.
If you have customized the content that vRealize Operations Manager provides such as alerts, symptoms,
recommendations, and policies, and you want to install content updates, clone the content before
performing the update. In this way, you can select the option to reset out-of-the-box content when you
install the software update, and the update can provide new content without overwriting customized
content.
This chapter includes the following topics:
“Obtain the Software Update PAK File,” on page 39

Obtain the Software Update PAK File
Each type of cluster update requires a specic PAK le. Make sure you are using the correct one.
Download the Correct PAK files
To update your vRealize Operations Manager environment, you need to download the right PAK le for the
clusters you wish to upgrade. Notice that only the Virtual Appliance clusters use an OS Update PAK le.
Host name entries in the /etc/hosts of each node might be reset when applying the OS update PAK le for
an update from vRealize Operations 6.0.x to version 6.1. You can manually update the hosts le after
completing the software update.

Create a Snapshot as Part of an Update
It's a good practice to create a snapshot of each node in a cluster before you update a
vRealize Operations Manager cluster. Once the update is complete, you must delete the snapshot to avoid
performance degradation.
For more information about snapshots, see the vSphere Virtual Machine Administration documentation.
Procedure
1 Log into the vRealize Operations Manager Administrator interface at https://<master-node-FQDN-or-
IP-address>/admin.
2 Click Take under the cluster status.
3 When all nodes are oine, open the vSphere client.
4 Right-click a vRealize Operations Manager virtual machine.
5 Click Snapshot and then click Take Snapshot.
a Name the snapshot. Use a meaningful name such as "Pre-Update."
b Uncheck the Snapshot the Virtual Machine Memory check box.
c Uncheck the Ensure Quiesce Guest File System (Needs VMware Tools installed) check box.
d Click OK.
6 Repeat these steps for each node in the cluster.
What to do next
Start the update process as described in “Install a Software Update,” on page 42.
How To Preserve Customized Content
When you upgrade vRealize Operations Manager, it is important that you upgrade the current versions of
content types that allow you to alert on and monitor the objects in your environment. With upgraded alert
denitions, symptom denitions, and recommendations, you can alert on the various states of objects in
your environment and identify a wider range of problem types. With upgraded views, you can create
dashboards and reports to easily identify and report on problems in your environment.
You might need to perform certain steps before you upgrade the alert denitions, symptom denitions,
recommendations, and views in your vRealize Operations Manager environment.
If you customized any of the alert denitions, symptom denitions, recommendations, or views that
n
were provided with previous versions of vRealize Operations Manager, and you want to retain those
customized versions, perform the steps in this procedure.
If you did not customize any of the alert denitions, symptom denitions, recommendations, or views
n
that were provided with previous versions of vRealize Operations Manager, you do not need to back
them up rst. Instead, you can start the upgrade, and during the upgrade select the check box named
Reset out-of-the-box content.
Prerequisites
You previously customized versions of your alert denitions, symptom denitions, recommendations, or
views.
Procedure
1 Before you begin the upgrade to vRealize Operations Manager, back up the changes to your alert
denitions, symptom denitions, recommendations, and views by cloning them.
40 VMware, Inc.
2 Start the upgrade of vRealize Operations Manager.
3 During the upgrade, select the check box named Reset out-of-the-box content.
After the upgrade completes, you have preserved your customized versions of alert denitions, symptom
denitions, recommendations, and views, and you have the current versions that were installed during the
upgrade.
What to do next
Review the changes in the upgraded alert denitions, symptom denitions, recommendations, and views.
Then, determine whether to keep your previously modied versions, or to use the upgraded versions.
Backup and Restore
Backup and restore your vRealize Operations Manager system on a regular basis to avoid downtime and
data loss in case of a system failure. If your system does fail, you can restore the system to the last full or
incremental backup.
You can backup and restore vRealize Operations Manager single or multi-node clusters by using
vSphere Data Protection or other backup tools. You can perform full, dierential, and incremental backups
and restores of virtual machines.
To backup and restore vRealize Suite components by using vSphere Data Protection and NetBackup, see the
Backup and Restore section in the vRealize Suite Information Center.
Chapter 6 Updating, Migrating and Restoring
N All nodes are backed up and restored at the same time. You cannot back up and restore individual
nodes.
vRealize Operations Manager Software Updates
vRealize Operations Manager includes a central page where you can manage updates to the product
software.
How Software Updates Work
The Software Update option lets you install updates to the vRealize Operations Manager product itself.

vRealize Operations Manager vApp Deployment and Configuration Guide
Migrate a vCenter Operations Manager Deployment into this Version
By importing data, an established or production version of vRealize Operations Manager can assume the
monitoring of a vCenter Operations Manager deployment.
You cannot migrate vCenter Operations Manager directly to this version of vRealize Operations Manager.
Instead, you follow a two-step process:
1 Migrate and import vCenter Operations Manager 5.8.x into vRealize Operations Manager 6.0.x as
described in the version 6.0.x documentation.
2 Use the vRealize Operations Manager Software Update option to update vRealize Operations Manager
6.0.x to this version.
N Make sure your vCenter Operations Manager 5.8.x and vRealize Operations Manager 6.0.x instances
are on the same physical network. Otherwise the data import may not work. Data import process fails when
source (vCenter Operations Manager 5.x) is separated from the destination vRealize Operations Manager 6.x
environment by a slow network connection (WAN). Data import over a connection that is slower than LAN
speed is not supported. For more information, see the Knowledge Base article 2141964.
