About vCenter Server Upgrade |
1 |
vCenter Server 6.7 provides many options for upgrading your vCenter Server deployment. For a successful vCenter Server upgrade, you must understand the upgrade options, the configuration details that impact the upgrade process, and the sequence of tasks.
The two core components of vSphere are VMware ESXi™ and VMware vCenter Server™. ESXi is the virtualization platform on which you can create and run virtual machines and virtual appliances. vCenter Server is a service that acts as a central administrator for ESXi hosts connected in a network. You use the vCenter Server system to pool and manage the resources of multiple hosts.
vCenter Server Appliance is a preconfigured Linux OS-based virtual machine optimized for running the vCenter Server system and the vCenter Server components.
Starting with vSphere 6.0, important required services for running vCenter Server and the vCenter Server components are included in the Platform Services Controller.
Based on your existing vCenter Server configuration details, you can upgrade to one of the following deployment types:
nvCenter Server with an embedded Platform Services Controller.
nvCenter Server with an external Platform Services Controller.
Important You cannot change your vCenter Server deployment type during upgrade.
This chapter includes the following topics:
nOverview of the vSphere Upgrade Process
nvSphere 6.7 Component Behavior Changes that Affect Upgrade
nDeployment Topologies with External Platform Services Controller Instances and High Availability
nMoving from a Deprecated to a Supported vCenter Server Deployment Topology Before Upgrade or Migration

vCenter Server Upgrade
Overview of the vSphere Upgrade Process
vSphere is a sophisticated product with multiple components to upgrade. Understanding the required sequence of tasks is vital for a successful vSphere upgrade.
Figure 1 1. Overview of High-Level vSphere Upgrade Tasks
Start vSphere upgrade
Back up your configuration
Upgrade vCenter Server
Upgrade ESXi hosts
Upgrade virtual machines and virtual appliances
Upgrade to vSphere 6.7 complete
Upgrading vSphere includes the following tasks:
1Read the vSphere release notes.
2Verify that you have backed up your configuration.
3If your vSphere system includes VMware solutions or plug-ins, verify that they are compatible with the vCenter Server or vCenter Server Appliance version to which you are upgrading. See VMware Product Interoperability Matrix at http://www.vmware.com/resources/compatibility/sim/interop_matrix.php.
4If your vSphere system includes Platform Services Controller, upgrade Platform Services Controller appliance 6.0 to version 6.7.
5Upgrade vCenter Server.
See Overview of the vCenter Server Upgrade Process.
6If you are using vSphere Update Manager, upgrade it. Refer to the VMware vSphere Update Manager documentation.

vCenter Server Upgrade
7To ensure sufficient disk storage for log files, consider setting up a syslog server for remote logging. Setting up logging on a remote host is especially important for hosts with limited local storage.
For detailed instructions, see ESXi Upgrade.
8Upgrade your VMs and virtual appliances, manually or by using vSphere Update Manager, to perform an orchestrated upgrade.
For detailed instructions, see ESXi Upgrade.
When you upgrade vSphere, you must perform all procedures in sequence to avoid possible data loss and to minimize downtime. You can perform the upgrade process for each component in only one direction. For example, after you upgrade to vCenter Server 6.7, you cannot revert to vCenter Server version 6.0 or version 6.5. With backups and some planning, however, you can restore your original software records.
Overview of the vCenter Server Upgrade Process
VMware provides many options to upgrade to vCenter Server 6.7.
You can upgrade or migrate your vCenter Server version 6.0 or version 6.5 installation to version 6.7 using the method that best addresses your deployment goals and requirements.

vCenter Server Upgrade
You can connect vCenter Server instances with external Platform Services Controller instances in an Enhanced Linked Mode configuration.
Important Although you can choose to join a vCenter Single Sign-On domain, you should consider vCenter Server with an embedded Platform Services Controller as a standalone installation and do not use it for replication of infrastructure data.
Concurrent upgrades are not supported and upgrade order matters. For information on upgrade order for transitional environments, see Upgrade or Migration Order and Mixed-Version Transitional Behavior for Multiple vCenter Server Instance Deployments.
vCenter Server Supported Upgrade Methods
Graphical User |
The GUI installer provides a two-step upgrade method using an OVA file |
Interface (GUI) Installer |
that you deploy, and the vCenter Server Appliance Management GUI. The |
|
first step deploys an unconfigured Platform Services Controller appliance or |
|
vCenter Server Appliance as an OVA file. The second step uses the |
|
vCenter Server Appliance Management GUI to configure the new appliance |
|
using the source deployment data. |
Command Line |
The CLI installer provides advanced users with a CLI method for upgrading |
Interface (CLI) Installer |
the vCenter Server Appliance or migrating vCenter Server on Windows to |
|
an appliance. You can upgrade or migrate to vCenter Server Appliance |
|
configurations using customized CLI templates. |
Migration Assistant |
When you migrate a legacy vCenter Single Sign-On, |
Interface for Migrating |
Platform Services Controller, or vCenter Server on Windows to an |
vCenter Server on |
appliance using the Migration Assistant interface. You can use either the |
Windows to |
GUI method or the CLI method to migrate the legacy Windows installation |
vCenter Server |
data to a target appliance. See Overview of Migration from vCenter Server |
Appliance |
on Windows to an Appliance. |
Deprecated vCenter |
When upgrading or migrating from deprecated deployment models, you |
Server Deployment |
must first migrate your deployment to a currently supported deployment |
Models |
model before attempting to upgrade or migrate it to a vCenter Server 6.7 |
|
deployment. For more information, see Moving from a Deprecated to a |
|
Supported vCenter Server Deployment Topology Before Upgrade or |
|
Migration |
Patching and Updating |
A patch or update brings the vCenter Server 6.7 software up to the current |
vCenter Server |
minor version on the existing physical or virtual machine. You can use the |
|
patching process to make minor upgrades to your 6.7 deployment. See |
|
Differences Between vSphere Upgrades, Patches, Updates, and Migrations |
|
and Chapter 7 Patching and Updating vCenter Server 6.7 Deployments. |

vCenter Server Upgrade
vCenter Server Upgrade Compatibility
The upgrade to vCenter Server 6.7 affects other software components of the data center.
Table 1 1 summarizes how upgrading vCenter Server can affect your data center components.
vCenter Server 6.7 can manage ESXi version 6.0 or 6.5 hosts in the same cluster with ESXi 6.7 hosts vCenter Server 6.7 cannot manage ESXi 5.5 or earlier hosts.
vSphere supports upgrades from vCenter Server 6.0 and later to vCenter Server 6.7. To upgrade from vCenter Server 5.0, 5.1 or 5.5, you must first upgrade the vCenter Server instance to version 6.0 or later releases, and then upgrade to vCenter Server 6.7. For information about upgrading vCenter Server 5.0, 5.1, or 5.5 to version 6.0 or 6.5, see the VMware vSphere 6.0 Documentation or VMware vSphere 6.5 Documentation
Table 1 1. Upgrading vCenter Server and Related VMware Products and Components
Product or Component |
Compatibility |
|
|
vCenter Server |
Verify support for the upgrade path from your current version of vCenter Server to your planned |
|
upgrade version. See the VMware Product Interoperability Matrix at |
|
http://www.vmware.com/resources/compatibility/sim/interop_matrix.php. |
|
|
vCenter Server database |
Verify that your database is supported for the vCenter Server version that you are upgrading to. |
|
Upgrade the database if necessary. See the VMware Product Interoperability Matrix at |
|
http://www.vmware.com/resources/compatibility/sim/interop_matrix.php. |
|
|
|
Note vCenter Server Appliance for version 6.7 uses PostgreSQL for the embedded database. |
|
vCenter Server Appliance 6.7 does not support external databases. |
|
|
|
|
vSphere Web Client |
Verify that your vSphere Web Client works with the vCenter Server version that you are |
|
upgrading to. For best performance and compatibility, upgrade your vSphere Web Client to the |
|
same version as your vCenter Server. See the VMware Product Interoperability Matrix at |
|
http://www.vmware.com/resources/compatibility/sim/interop_matrix.php. |
|
|
ESX and ESXi hosts |
Verify that your ESX or ESXi host works with the vCenter Server version that you are upgrading |
|
to. vCenter Server 6.7 requires ESXi host version 6.0 or later. Upgrade if necessary. See the |
|
VMware Product Interoperability Matrix at |
|
http://www.vmware.com/resources/compatibility/sim/interop_matrix.php. |
|
|
VMware Host Profiles |
Host Profiles is a vCenter Server tool for designing and deploying ESX and ESXi hosts. Ensure |
|
that you are using Host Profiles version 6.0 or later. See Knowledge Base article KB 52932. |
|
For more information on upgrade issues related to Host Profiles, see Upgrade Issues with |
|
vCenter Server Containing Host Profiles and the sections on recommended Host Profiles |
|
upgrade workflows in the vSphere Host Profiles documentation. |
|
|
VMFS-3 volumes |
ESXi and vCenter Server supports VMFS3, VMFS5, and VMFS6 datastores. You can continue to |
|
use existing VMFS-3 datastores, but you cannot create new VMFS-3 datastores. If you have |
|
VMFS-3 datastores, upgrade them to VMFS-6. For more information on VMFS datastores, see |
|
the vSphere Storage documentation. |
|
|
Virtual machines |
Upgrade options depend on your current version. See the information about upgrading virtual |
|
machines in the ESXi Upgrade documentation. |

vSphere Distributed Virtual |
You must upgrade to DVS version 6.0 or later prior to upgrading to vCenter Server 6.7. See |
Switch (DVS) |
Knowledge Base article KB 52826. |
|
|
vSphere Network I/O Control |
DVS version 6.0 or later supports only Network I/O Control version 3. If you are using an earlier |
|
version of Network I/O Control you must upgrade to Network I/O Control version 3. For more |
|
information, see the vSphere Networking documentation. |
|
|
vSAN |
Synchronize versions of vCenter Server and ESXi to avoid potential faults because of differences |
|
in the vSAN support in vCenter Server and ESXi. For the best integration between vSAN |
|
components on vCenter Server and ESXi, deploy the latest version of these two vSphere |
|
components. For more information, see the ESXi Installation and Setup, vCenter Server |
|
Installation and Setup, ESXi Upgrade, and vCenter Server Upgrade documentation. |
|
|
vSAN disk version |
vSAN has several different on-disk format versions available depending on the version and |
|
upgrade history of the cluster. Some on-disk format versions are transient while others are |
|
intended for long-term production. As certain vSAN features are tied to the on-disk format |
|
version, the format version must be accounted for when determining interoperability. See |
|
Knowledge Base article KB 2145267. |
|
|
Legacy Fault Tolerance |
If the vCenter Server inventory contains a VM on which legacy VMware Fault Tolerance (FT) is in |
|
use, upgrade or migration will be blocked until you turn off this feature. For information about |
|
legacy FT, see Knowledge Base article KB 2143127. For information on disabling or turning off |
|
FT, see Knowledge Base article KB 1008026. |

Upgrade or Migration Order and Mixed-Version Transitional Behavior for Multiple vCenter Server Instance Deployments
When you upgrade or migrate a deployment with multiple vCenter Server instances, the upgrade or migration order matters.
You upgrade or migrate externally deployedPlatform Services Controller 6.0 and 6.5 instances first. You temporarily leave the vCenter Server instances at version 6.0 or version 6.5 while you complete the upgrade or migration process for thePlatform Services Controller 6.0 or 6.5 instances.
nYou must upgrade or migrate your Platform Services Controller 6.0 or 6.5 instances sequentially.
nFor a mixed-platform installation with Platform Services Controller 6.0 or 6.5 instances on Windows and vCenter Server Appliance instances, upgrade or migrate all the Platform Services Controller 6.0 or 6.5 instances on Windows before upgrading any vCenter Server Appliance instances.
nFor a mixed-platform installation with Platform Services Controller 6.0 or 6.5 appliances and
vCenter Server instances on Windows, upgrade all Platform Services Controller 6.0 or 6.5 appliances before upgrading or migrating any vCenter Server instances on Windows.
nAfter upgrading or migrating your Platform Services Controller 6.0 or 6.5 instances, you can upgrade vCenter Server instances. vCenter Server instances that point to the same
Platform Services Controller can be upgraded or migrated concurrently.
When you upgrade an externally deployed Platform Services Controller 6.0 instance to an externally deployed Platform Services Controller 6.7 instance, the legacy vCenter Server instances that were using the component are not affected. The legacy vCenter Server instances continue to operate with the upgraded Platform Services Controller just as they operated before the upgrade without any problems or required reconfiguration. Legacy vCenter Server instances continue to be visible to the legacy
vSphere Web Client, though vCenter Server 6.7 instances are not visible to the legacy vSphere Web Clients.
Transitional behavior during a migration from a vCenter Server deployment on Windows to an appliance deployment is the same as for a vCenter Server upgrade on Windows.
Mixed-version transitional behavior is the same for vCenter Single Sign-On instances deployed in vCenter Server vCenter Server Appliance environments.

Important Mixed-version environments are not supported for production. Use these environments only during the period when an environment is in transition between vCenter Server versions.
The transitional order and behavior are the same for vCenter Server 6.0 or 6.5 environments when upgrading or migrating to vCenter Server 6.7 environments. The vCenter Server 6.0 instances continue operating with the Platform Services Controller 6.7 instance as they did before the upgrade or migration, without any problems or required action.
The only action required for a mixed-version environment after transition is a restart of any legacy vSphere Web Client instances if they will be used to view vCenter Server instances that are not yet upgraded or migrated.

After upgrading the first vCenter Server instance to 6.7, changes occur in the connectivity between the vCenter Server instances.
nThe two remaining legacy vSphere Web Client instances can no longer view the newly upgraded vCenter Server 6.7 instance after it joins the Platform Services Controller instance.
nThe legacy vSphere Web Client instances can still view the legacy vCenter Server instances after they are restarted.
nThe vSphere Web Client 6.7 instance that is part of the newly upgraded vCenter Server 6.7 instance can view the legacy vCenter Server instances and 6.7 instances.
After upgrading the second vCenter Server instance to 6.7, further changes occur in the connectivity between the vCenter Server instances:
nLinked Mode functionality is replaced by Enhanced Linked Mode functionality between the newly upgraded vCenter Server 6.7 instances after they are joined to the Platform Services Controller.

nThe vSphere Web Client 6.7 instances can view all the vCenter Server 6.7 instances.
Di€erences between Upgrading and Migrating vCenter Server on Windows
You have two choices for moving your vCenter Server deployment on Windows to version 6.7: you can use the upgrade on Windows process or you can use the migration process to convert your deployment to an appliance at the same time that you upgrade the deployment to version 6.7.
It is important to understand the differences and similarities between upgrading and migrating vCenter Server instances on Windows.
nChoose the upgrade on Windows process to upgrade a vCenter Server version 6.0 or version 6.5 deployment on Windows to a vCenter Server 6.7 deployment on Windows. For details, see Chapter 2 Upgrading vCenter Server for Windows.
nChoose the migration to an appliance process to convert a vCenter Server version 6.0 or version 6.5 deployment on Windows to a vCenter Server Appliance 6.7 deployment. For details, see Chapter 4 Migrating vCenter Server for Windows to vCenter Server Appliance.
You can migrate the following vCenter Server deployment types from Windows to appliances while upgrading to version 6.7:
nvCenter Server with an embedded Platform Services Controller (version 6.0 or 6.5)
nvCenter Server with an external Platform Services Controller (version 6.0 or 6.5)
VMware, Inc. |
18 |
vCenter Server Upgrade
You can migrate with an embedded or external vCenter database. In either case, the database is converted to an embedded PostgreSQL database on the new appliance. For more about the database migration, see Preparing vCenter Server Databases for Migration.
You can migrate a vCenter Server installation to an appliance using either the GUI method or CLI method.
nWhen migrating vCenter Server with an embedded Platform Services Controller (version 6.0 or 6.5), the migration is a single workflow.
nWhen migrating vCenter Server with an external Platform Services Controller (version 6.0 or 6.5), migration order matters. You migrate Platform Services Controller instances before migrating vCenter Server instances. For details, see Chapter 4 Migrating vCenter Server for Windows to vCenter Server Appliance.
Preparation includes using VMware Migration Assistant to gather the required information on the source vCenter Server instance or Platform Services Controller instance. For details, see Download and Run VMware Migration Assistant on the Source Windows Machine.
Upgrading or Migrating to vSphere License Service
The License Service is in the Platform Services Controller. The License Service provides common license inventory and management capabilities to the vCenter Server systems that are registered to a
Platform Services Controller or multiple Platform Services Controllers that are joined in one vCenter Single Sign-On domain.
During the upgrade of the vCenter Server systems that are connected to a Platform Services Controller, their licensing data is transferred to the License Service. The licensing data includes the available licenses and license assignments for hosts, vCenter Server systems, vSAN clusters, and other products that you use with vSphere.
After the upgrade or migration of the vCenter Server systems completes, the License Services stores the available licenses and manages the license assignments for the entire vSphere environment. If your vSphere environment consists of multiple Platform Services Controllers joined in one vCenter Single Sign-On domain, the License Service in every Platform Services Controller contains a replica of the licensing data for the entire environment.
For more information about the License Service and managing licenses in vSphere, see vCenter Server and Host Management.
Di€erences Between vSphere Upgrades, Patches, Updates, and
Migrations
vSphere products distinguish between upgrades, which make major changes to the software, patches and updates, which make smaller changes to the software, and migrations, which make changes to the software platform.
VMware product versions are numbered with two digits, for example, vSphere 6.7. A release that changes either digit, for example, from 6.0 to 6.5, or from 6.5 to 6.7, involves major changes in the software, and requires an upgrade from the previous version. A release that makes a smaller change, requiring only a patch or update, is indicated by an update number, for example, vSphere 6.0 Update 1.
VMware, Inc. |
19 |
vCenter Server Upgrade
For information about upgrading vCenter Server installations, see Chapter 3 Upgrading the vCenter Server Appliance and Platform Services Controller Appliance or Chapter 2 Upgrading vCenter Server for Windows.
For information about patching or updating vCenter Server, see Chapter 7 Patching and Updating vCenter Server 6.7 Deployments
When you upgrade an ESXi host, some host configuration information is preserved in the upgraded version, and the upgraded host, after rebooting, can join a vCenter Server instance that has been upgraded to the same level. Because updates and patches do not involve major changes to the software, host configuration is not affected. For more information, see the ESXi Upgrade documentation.
When you upgrade a vCenter Server for Windows instance and at the same time convert it to a vCenter Server Appliance instance, it is a migration.
For information about migrating a vCenter Server installation to an appliance, see Chapter 4 Migrating vCenter Server for Windows to vCenter Server Appliance.
Support for Federal Information Processing Standard 140-2
vCenter Server 6.7 supports Federal Information Processing Standard (FIPS) 140-2.
FIPS 140-2 is a U.S. and Canadian government standard that specifies security requirements for cryptographic modules. By default, FIPS 140-2 is always enabled after installation or upgrade of vCenter Server 6.7.
To learn more about support for FIPS 140-2 in VMware products, see https://www.vmware.com/security/certifications/fips.html.
To learn how to enable or disable FIPS 140-2 support, see the vSphere Security documentation.
Support for Transport Security Layer 1.2
By default, vSphere 6.7 supports the Transport Security Layer (TLS) 1.2 encryption protocol. The upgrade or migration to vCenter Server 6.7 disables the TLS 1.0 and TLS 1.1 encryption protocols, and you may need to reconfigure other VMware products and third-party products to use TLS 1.2.
During both upgrade and migration from vCenter Server 6.0 and 6.5 to vCenter Server 6.7, a notification message informs you that only the TLS 1.2 protocol is enabled. If you need to use the TLS 1.0 and TLS 1.1 protocols to support products or services that do not support TLS 1.2, you can use the TLS Configurator Utility to enable or disable the different TLS protocol versions. You can disable TLS 1.0, or you can disable both TLS 1.0 and TLS 1.1.
When upgrading a Platform Services Controller instance that manages one or more vCenter Server 6.0 or 6.0U1 instances which rely on the older protocols, TLS 1.0 and TLS 1.1 remain enabled to avoid a loss of connectivity. After the upgrade or migration to vCenter Server 6.7 is complete, run the TLS Configurator Utility on each Platform Services Controller node to disable the less secure TLS 1.0 and TLS 1.1 protocols, and use the TLS 1.2 protocol.
VMware, Inc. |
20 |
vCenter Server Upgrade
For a list of VMware products that support disabling TLS 1.0 and TLS 1.1, see VMware Knowledge Base article 2145796. To learn how to manage TLS protocol configuration, and use the TLS Configurator Utility, see the VMware Security documentation.
Deployment Topologies with External
Platform Services Controller Instances and High Availability
To ensure Platform Services Controller high availability in external deployments, you must install or deploy at least two joined Platform Services Controller instances in your vCenter Single Sign-On domain. When you use a third-party load balancer, you can ensure an automatic failover without downtime.

You can use a third-party load balancer per site to configure Platform Services Controller high availability with automatic failover for this site. For information about the maximum number of
Platform Services Controller instances behind a load balancer, see the Configuration Maximums documentation.
Important To configure Platform Services Controller high availability behind a load balancer, the Platform Services Controller instances must be of the same operating system type. Mixed operating systems Platform Services Controller instances behind a load balancer are unsupported.
The vCenter Server instances are connected to the load balancer. When a Platform Services Controller instance stops responding, the load balancer automatically distributes the load among the other functional Platform Services Controller instances without downtime.

When you join two or more Platform Services Controller instances in the same site with no load balancer, you configure Platform Services Controller high availability with a manual failover for this site.
Note If your vCenter Single Sign-On domain includes three or more Platform Services Controller instances, you can manually create a ring topology. A ring topology ensures Platform Services Controller reliability when one of the instances fails. To create a ring topology, run the /usr/lib/vmwarevmdir/bin/vdcrepadmin -f createagreement command against the first and last
Platform Services Controller instance that you have deployed.

Moving from a Deprecated to a Supported vCenter Server Deployment Topology Before Upgrade or Migration
Before you upgrade or migrate your environment to vSphere 6.7, you must move any deprecated deployment topology to a supported deployment topology.
When you first install vCenter Server 6.0 or 6.5, your deployment includes either an embedded Platform Services Controller or vCenter Single Single-On, or an external Platform Services Controller or vCenter Single Single-On.
If you upgrade or migrate your deployment later you have two options:
nJoin a vCenter Server with an external Platform Services Controller to a Platform Services Controller.
nJoin an external Platform Services Controller to a Platform Services Controller.
The installer does not validate whether the Platform Services Controller is external or embedded with vCenter Server. Although many types of join operations are possible, not all resulting topologies are supported. Before you upgrade or migrate your environment to vSphere 6.7, you must move any deprecated deployment topology to a supported deployment topology.

If you have multiple systems configured for high availability, vCenter Server enables you to incorporate your common services into an external Platform Services Controller configuration as part of your upgrade process.
If you have a multi-site setup configured with replication, you can use vCenter Server to incorporate your common services into an external Platform Services Controller configuration as part of your upgrade process.
For more information on mixed version transitional environments, see Upgrade or Migration Order and Mixed-Version Transitional Behavior for Multiple vCenter Server Instance Deployments.

vCenter Server Upgrade
You can migrate a vCenter Server version 6.0 or 6.5 instance on Windows to a vCenter Server Appliance 6.7 deployment on a Linux-based OS.
The vCenter Server example migration paths demonstrate supported migration outcomes.
You can migrate a vCenter Server instance with an embedded Platform Services Controller (version 6.0) to a vCenter Server Appliance 6.7 instance with an embedded Platform Services Controller appliance. In this case the software migrates the vCenter Server instance and the embedded
Platform Services Controller instance at the same time.

vCenter Server Upgrade
You cannot uninstall or reinstall individual services during the upgrade process.
Note Starting with vSphere 6.5, the vCenter Server services are not standalone services under Windows SCM, instead they run as child processes of the VMware Service Lifecycle Manager service.
vCenter Server for Windows Requirements
To upgrade vCenter Server on a Windows virtual machine or physical server, your system must meet specific hardware and software requirements.
nSynchronize the clocks on all machines running the vCenter Server services. See Synchronizing Clocks on the vSphere Network.
nVerify that the system network name of the machines running vCenter Server services are valid, and are reachable from other machines in the network.
nVerify that the host name of the virtual machine or physical server on which you are upgrading vCenter Server complies with RFC 1123 guidelines.
nIf your vCenter Server service is running in a user account other than the Local System account, verify that the user account in which the vCenter Server service is running has the following permissions:
n Member of the Administrators group n Log on as a service
n Act as part of the operating system (if the user is a domain user)
Note Starting with vSphere 6.5, the vCenter Server services run as child processes of the VMware Service Lifecycle Manager service.
nVerify that the local policy of the virtual machine or physical server on which you are upgrading vCenter Server allows assigning Log on as a batch job rights to new local users.
Note Starting with vSphere 6.5, some vCenter Server processes use separate local users that are automatically created and added to the local security policy Log on as a batch job. Such new local users are cm, content-library, eam, imagebuilder, mbcs, netdumper, perfcharts, rbd, vapiEndpoint, vmware-vpostgres, vsan-health, vsm, vsphere-client, and vsphere-ui.
nVerify that the LOCAL SERVICE account has read permission on the folder in which vCenter Server is installed and on the HKLM registry.
nVerify that the connection between the virtual machine or physical server and the domain controller is working.
