GUI Migration of vCenter Server with an External Platform Services Controller to an Appliance

You can use the GUI to migrate vCenter Server with an external Platform Services Controller to a vCenter Server appliance.

Before migrating a vCenter Server deployment with an external Platform Services Controller, you must first converge the external Platform Services Controller to an embedded Platform Services Controller and then perform the migration. See Knowledge Base article KB 68137.

If you use Update Manager in the vCenter Server deployment on Windows that you migrate, and Update Manager runs on a separate machine from any other of the vCenter Server components, take an extra step to migrate Update Manager to an appliance.

1. If your vCenter Server deployment on Windows uses an external Update Manager, run Migration Assistant on the Update Manager machine to start the migration of the Update Manager server and database to the Update Manager appliance.
2. Migrate the vCenter Server instance from Windows to a vCenter Server appliance.
3. Verify the newly migrated vCenter Server appliance.
4. Decommision the Platform Services Controller.

GUI tasks for migrating an external Platform Services Controller instance from Windows to an appliance.

1. Download and Mount the vCenter Server Installer ISO file on a network virtual machine or physical server from which you want to perform the migration.
2. Download and Run VMware Migration Assistant on the Source Windows Machine.
   Note: If you are migrating a vCenter Server system that uses an external instance of Update Manager that runs on a separate Windows machine, first run Migration Assistant on the Update Manager machine.
3. Assemble the Required Information for Migrating vCenter Server from Windows to an Appliance for each Platform Services Controller or vCenter Server instance.
4. Deploy the OVA File for the Target vCenter Server Appliance
5. Set Up the Target vCenter Server Appliance

Important: The user name you use to log in to the physical machine from which you want to run the GUI installer, the path to the vCenter Server appliance installer, and values, including the passwords, must contain only ASCII characters. Extended ASCII and non-ASCII characters are unsupported.

For each node to be migrated, the installer:

• Deploys a new target appliance.
• Exports the required files from the source Platform Services Controller or vCenter Server instance.
• Copies the required files to the target appliance for migration.
• Runs the migration process on the target appliance as indicated in the Summary.
• Imports and updates the files and settings of the source Platform Services Controller or vCenter Server instance to the new vCenter Server appliance.

Deploy the OVA File for the Target vCenter Server Appliance

To start the migration process, you use the GUI installer to deploy the OVA file that is included in the installer ISO file as the target vCenter Server appliance.

16. Wait for the OVA deployment to finish, and click Continue to proceed with stage 2 of the deployment process to set up and start the services of the newly deployed appliance.
    Note: If you exit the wizard by clicking Close, you must log in to the vCenter Server Management Interface to set up and start the services.

Results

The newly deployed target vCenter Server appliance version 8.0 is running on the target server but is not yet configured.

Important: The data from the source vCenter Server is not yet transferred and the services of the target appliance are not started.

Set Up the Target vCenter Server Appliance

When the OVA deployment finishes, you are redirected to stage 2 of the migration process to transfer the data from the source vCenter Server and start the services of the newly deployed target vCenter Server appliance.

The period of time during which your system is unavailable does not begin until you start to set up the target appliance. You cannot cancel or interrupt the process until it finishes with the shutdown of the source deployment. The time your system is unavailable ends when the target appliance starts.

Procedure

1. Review the introduction to stage 2 of the migration process and click Next.
2. On the Select source vCenter Server page, enter the vCenter Single Sign-On administrator password and the root password of the source vCenter Server, enter the password of the user with administrative privileges on the vCenter Server instance, and click Next.
3. (Optional) Accept the warning message, if any, by clicking Yes.
4. If your source Windows machine is connected to an Active Directory domain, enter the credentials for an administrator domain user with permission to add the target machine to the Active Directory domain, and click Next.
   Note: The installer verifies the entered credentials, but does not check the required privileges to add the target machine to the Active Directory domain. Verify that the user credentials have all the required permissions to add a machine to the Active Directory domain.
5. Specify the replication topology for the vCenter Server. When converging vCenter Server instance with an external Platform Services Controller you must specify the replication topology.

   Convergence is the process of converting a vCenter Server instance with an external Platform Services Controller to a vCenter Server instance with those services embedded in the appliance.

   • This is the first vCenter Server in the topology that I want to converge.
   • This is a subsequent vCenter Server.

     If this is a subsequent vCenter Server, provide the IP address of its partner vCenter Server and its HTTPS port.

6. On the Select migration data page, choose the types of data that you want to transfer from the source vCenter Server to the target appliance.
   The large amount of data requires more time to be transferred to the new appliance.
7. On the ready to complete page, review the migration settings, accept the backup acknowledgment, and click Finish.
8. Click OK to confirm the shutdown of the source vCenter Server.
9. Wait for the data transfer and setup process to finish. Click OK to go to the vCenter Server Getting Started page.

Results

vCenter Server is migrated from Windows to a newly deployed target vCenter Server appliance. The source vCenter Server is powered off and the target appliance starts.

What to do next

• Verify Your vCenter Server Upgrade or Migration Is Successful.
• Upgrade all vCenter Server instances in the vCenter Single Sign-On domain.
• After converging a vCenter Server with an external Platform Services Controller node to a vCenter Server appliance, you must decommission the original external Platform Services Controller. Decommissioning a Platform Services Controller shuts it down and removes it from the single sign-on domain. See Decommission the Platform Services Controller.
• For post-migration steps, see After Upgrading or Migrating vCenter Server.

• You can configure high availability for the vCenter Server appliance. For information about providing vCenter Server appliance high availability, see vSphere Availability.
