I have 4 x DC's.. The previous admin got DC happy.. One of the DC's I plan to convert from a physical machine to a virtual machine. I plan on making a system state backup prior to the conversion. Currently it's carrying all of the FSMO roles. Should I transfer the roles to a different DC prior to converting/moving it? I figure the safest route would be to transfer the roles for I didn't want the version that I would mount causing odd AD replication issues for it would be slightly older copy of the replica than the others. I figure transferring the roles would best. Or.. Should I simply transfer the roles, demote it, and then assign it's IP to one of the other DC's since it currently answers DNS requests? I do have a DC that's on an Exchange server but I'm not messing with it.. At least not for now.
