When you intend to migrate your vCenter Server that runs on Windows to a vCenter Server Appliance, if your vCenter Server deployment uses Update Manager, additional steps might be required to move Update Manager to a new host machine manually.

You must move the Update Manager server and database in the following cases:

  • Update Manager 5.5, vCenter Server and vCenter Single Sign-On 5.5 run on the same machine.

  • Update Manager 5.5, and vCenter Single Sign-On 5.5 run on the same machine.

If Update Manager 5.5 runs on a different machine than vCenter Server 5.5 and vCenter Single Sign-On 5.5, after vCenter Server successfully migrates to vCenter Server Appliance, upgrade Update Manager.

vCenter Server Deployment Uses Embedded Update Manager

If Update Manager, vCenter Server, and vCenter Single Sign-On 5.5 run on the same machine, or if Update Manager 5.5 and vCenter Single Sign-On 5.5 run on the same machine, perform the following steps:

  1. Move the Update Manager Server and Database to a New Host Machine.

  2. Migrate vCenter Server 5.5 or vCenter Single Sign-On to an appliance. See 5.5 and Migration of vCenter Server with an External vCenter Single Sign-On to an Appliance

  3. Upgrade Update Manager to the same version as the target vCenter Server Appliance, and connect Update Manager to the target vCenter Server Appliance. For more information on how to upgrade Update Manager, see the vSphere Update Manager documentation.

vCenter Server Deployment Uses External Update Manager

If Update Manager runs on a different machine than vCenter Server 5.5 and vCenter Single Sign-On 5.5, perform the following steps:

  1. Migrate vCenter Server 5.5 or vCenter Single Sign-On 5.5 to an appliance. See Migration of vCenter Server with an Embedded vCenter Single Sign-On to an Appliance and Migration of vCenter Server with an External vCenter Single Sign-On to an Appliance

  2. Upgrade Update Manager to the same version as the target vCenter Server Appliance, and connect Update Manager to the target vCenter Server Appliance. For more information on how to upgrade Update Manager, see the vSphere Update Manager documentation.
