What final steps do I need to perform to get rid of the 2003 server that was successfully migrated to our new 2010 server? I don't see any references to it, unless I run the best practices analyzer which shows 2 servers and 2 administration groups. The old server is powered off, but I have had a couple of weird things happen that make me think it would be good to remove all references to it from the 2010 server.
I'll be doing another migration at a separate office in a couple of weeks, would like to do it as seamlessly as possible. Any help that someone can provide would be greatly appreciated.
