Imagine our AD domain is currently called DOMAIN1 but we want it to be called DOMAIN2. I know that we can't rename the domain because we've got Exchange servers in there so basically we're looking at a relatively major migration project. Parking servers & computers for now but we've got a reasonable number of users accounts and groups in DOMAIN1 and we'd like the exactly same in DOMAIN2.
So for example, my user account is domain1\rob.nicholson in the "IT Support" OU and I'm a member of domain1\group1 and domain1\group2. So OU "domain2\IT Support" needs creating (with same metadata), domain2\rob.nicholson needs creating (copying metadata again), domain2\group2 created, me added to it etc etc.
I'm looking for a tool that will, in effect, duplicate the AD structure in domain1 in domain2 for some objects, but not all (e.g. don't bother with computers).
Do such tools exist or am I barking up completely the wrong tree? No problem with considering commercial tools.
Suggestions for a good search term for this process appreciated as well.
