Out of nowhere I get three different sources asking me how to clean up old servers out of the RMS infrastructure. I was hesitant to tell folks to go poking around in the RMS configuration database. However the edits are benign enough and we all back up our databases so I put it out there.
In my opinion this is a purely cosmetic “issue.” In one place do you readily see the old servers referenced anywhere. It does not affect the functionality of the RMS infrastructure. Yet some feel this is important enough to open a support case and fix.
