The other day while upgrading our test System Center Operations Manager 2012 environment from the beta release of SP1 to the full release of SP1 our primary management server upgrade failed. When I went back to try the upgrade again the install didn’t see the existing installation. I had to re-install the management server which I ran into a few issues. When I tried to select the SQL server and current operational database the field was blank.
At this point I had done a some research and found that this is normal in cases where the old management server is still showing in the SCOM Console. So deleting the server and re-installing would be my next step. However, since this server was not only my RMS Emulator it also managed about 90% of our clients and I couldn’t just delete it from the management group.
So, using the Operations Manager Power Shell cmdlets as follows I was able to transfer the RMS Role to another management server.
I also had to changed primary management server on all the clients that had been managed by the Management server over to another management server.
Once this was done I was able to delete the old management server and re-install SP1 without an issue.
