We have a new 2008 R2 server to be replacing a 2003 R2 server (which is a DC and has DNS/DHCP/DFS/etc.). Here's an outline of my plan...
- Rename the old server to ServerOld
- Give the new server the name of the original server (Let's say Server)
- Migrate all services to the new server
- Demote ServerOld from being a DC and unjoin it from the domain
Are there any issues arising from renaming a DC and then giving a new server its old name immediately afterward?
