Can anyone give me any clues as to the best way to do this? I have one domain (the smaller) that I need to migrate to the other (the bigger). The smaller one has approx 25 users, and runs SQL for a schools package for students and all the extra that goes with that such as general ledger etc. I want to keep the domain controller as a member server (demoted) but move all the users into the main domain and set up security and so on there. The smaller domain runs on a different range of Ip numbers. I believe I can just add a scope to the bigger domain and put that range in there. I presume I won't need DNS running on the demoted server or DHCP? How would other people tackle this problem and can anyone advise any papers I can read. Any help would be appreciated. What about profiles and home directories and a multitude of other things that I have probably not thought of?
