I am planning an upgrade from Windows NT to Windows 2003 Active Directory. There's a new server that's been purchased and I will be installing Windows server 2003 x64 on it. I've been reading thru the upgrade guides but I need some advice.
I'd like to do as little as possible with the users' computers.
1. I would like to know if it's possible to perform a clean installation on the new server. (create a domain with the same name, move all the accounts from the old server to the new one, then power off the old server).
2. What will happen to all the client machines? Do they have to unjoin/rejoin the domain? Will I have to re-do user profiles?
3. Would it be any easier to upgrade the current NT 4.0 PDC to Windows 2003 and Active Directory and make the new server a domain controller and then decomission the old server?
I've just had better luck in the past doing clean installs rather than upgrades. What do you think?
4. I know there's the Active Directory Migration Tool available. Does that work pretty well or are there any other tools available?
