We are planning a migration from an environment in which approximately 400 workstations are connected to a Samba based domain. The Samba version is 3.5.4 and we are now planning for migrating these workstations to an Active Directory domain with Windows Server 2008 R2 functional level. In our Samba domain, users have roaming profiles and in the 2008R2 domain there should also be roaming profiles. Hence, we need to be able to move the user profiles from the Samba domain to the 2008R2 domain in the easiest way possible.
We have been looking into some different tools for performing this migration, including Microsoft Active Directory Migration Tool (ADMT) in version 3.2, 3.1 and 3.0. As for 3.2 and 3.1, they both have been claiming that they don't support lecacy domains such as Windows 2000 or NT4, as soon as we have tried to connect to the Samba domain.
What are the potential solutions for this migration? Have anyone of you successfully migrated in an equivalent or similar scenario?
Any input much appreciated.
