VCSA 6.0 > 6.5 upgrade error – VUM migration

Quick post, came across the following error when trying to upgrade from 6.0 > 6.5;

Check that VMware vCenter Server at ‘’ is up and running, and that the credentials are valid”.

To resolve this issue try the following;

  • Login your VUM server
  • Browse to C:\Program Files (x86)\VMware\Infrastructure\Update Manager
  • Run the VMwareUpdateManagerUtility.exe then login.
  • Then “re-register vCenter Server”
  • Restart “VMware Update Server Service”

Then have another bash at the upgrade!
