The primary DC is being taken out of production. It also does DHCP, WINS & DNS. I have 2 other servers that are secondary domain controllers and the one that is going to become the primary already has the global catalogs and FISMO roles. I have several questions.
1. What do I do first? Move the DHCP, WINS and DNS before I demote the primary DC? I wasn't sure if it matter which order this is done.
2. I found some instructions for moving DHCP, but they differ somewhat. Some articles say you have to copy registry entries, but I found a Microsoft article that doesn't mention copying the registry entries.
3. I've done a ton of research on moving this stuff, but it conflicts so much that I wanted to see if someone does have good instructions for this. While I support all of the servers, I haven't done much with dhcp, dns & wins.
4. Should I do this all at one time or one by one?
Thanks - I know this is a long list.
