Before making any changes make sure you take a snapshot of vCenter server.
How big/complicated is your vSphere environment?
If it's complicated setup and deploying a new vCSA is not an option, suggest you to open a SR with GSS.
Thank you for the advice. Yes the vCenter Server is complicated enough we would prefer not to have to reconfigure the resource pools/drs/and distributed switches
