I recently needed to decommission a VCSA and external PSC. Following the VMWare KB 2106736 I proceeded to decomission the servers usign the cmsso utility.
Decommission vCenter — connected to the PSC it is registered with and:

Error again. Some googling led me to techbrainblog’s excellent page on using these utilities and also the solutions to some common but cryptic errors. Very useful. The solution to this error in particular is to simply shut down the old PSC. It needs to be offline before the command is ran.
Good to go!
