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

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

When you migrate from vCenter Server with an embedded Platform Services Controller on Windows to vCenter Server appliance, the entire deployment is migrated in a single step.

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 with embedded Platform Services Controller from Windows to a vCenter Server appliance.

GUI tasks for migrating vCenter Server with an embedded Platform Services Controller from Windows to a vCenter Server 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.
4. Deploy the OVA File for Migrating to the Target vCenter Server Appliance.
5. Set Up the Target vCenter Server Appliance

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

The installer:

• Deploys a new target appliance.
• Exports the required files from the source vCenter Server.
• Copies the required files to the new vCenter Server appliance.
• Runs the migration process on the new vCenter Server appliance as specified in the Summary.
• Imports and updates the files and settings of the source vCenter Server installation to the new vCenter Server appliance.

Deploy the OVA File for Migrating to 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.
