I have a question about domain joining workstations. We just upgraded Exchange and AD to a new server. I want to know how I join these old workstations to the new domain controller and preserve all the users documents etc.

In other words I don't want to create another user account on the workstations.

Thanks for all your help.

Are you saying that the old AD server is already dead or you are wanting advice to migrate? – Jim B Jun 1 '10 at 19:11

Is the new server a member of the old domain? If they are part of the same domain, then you don't have to do anything.

We are putting the old server to rest. – ekamtaj Jun 1 '10 at 18:58
Yes, but you still haven't answered the critical question. Is your new server a DC in the same domain as the old server, or did you create a completely new forest/domain? – Zoredache Jun 1 '10 at 19:15
We created completly new forest/domain – ekamtaj Jun 2 '10 at 13:11

You are not creating another user account but your creating another user profile.

  1. Create two way trust relation between the two domains.
  2. Install ADMT.
  3. Read ADMT migration guide. If you move the user and computer accounts from the source domain it should keep the sids so you won't need to re-configure the user profile. Exchange is whole nother story.
