I currently have a AD server that does multiple roles- AD/ DNS/ File server/ printserver. The domain is currently called domain.com, i would like to move AD and DNS to a new server and change it to domain.local . The old server would only be used as a file and print sever. What would be the best way to do this procedure? i want to be able to move the OU's and thier group policy over as well. Will i have to rejoin all the users to the new domain.local and move thier profile settings.
