Moving Update Manager to a New Host Machine When Migrating
vCenter Server to vCenter Server Appliance
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:
n
Update Manager 5.5, vCenter Server and vCenter Single Sign-On 5.5 run on the same machine.
n
Update Manager 5.5, and vCenter Single Sign-On 5.5 run on the same machine.
If Update Manager 5.5 runs on a dierent 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.
