I want to run this by everyone to see what I'm missing and what "gotchas" are lurking.
Scenario: We purchased a company with a variety of site locations and we're migrating a domain in one city (DomainCityNew) into our production domain (DomainProd), while keeping some of the original domain (DomainCityOld) intact. They will be getting all new PC's.
Goal: I need to have the servers up and running, file server access, printing functions working and the users/groups moved to our domain. Their existing domain controller can be demoted to a member server.
Caveat: I cannot use a trust between the two domains, and so I'm doing this manually instead of using ADMT.
From a high level perspective, I have:
Transfer FSMO roles to DomainControllerA, which will remain at the DomainCityOld site.
Re-IP the servers that we are keeping
Join servers to DomainProd domain
Import AD accounts into DomainProd
Assign/Create group memberships in DomainProd
