Q: Does Windows Server 2012 include a version of the Active Directory Migration Tool?
A: The latest version of the Active Directory Migration Tool (ADMT), version 3.2, is for Windows Server 2008 R2. ADMT 3.2 isn't supported on Windows Server 2012, and there are currently no plans for a Windows Server 2012 version.
You can download ADMT 3.2 from the Microsoft Download Center. For organizations that want to migrate to Windows Server 2012 and still use ADMT, the solution is to install the tool on a Windows Server 2008 R2 server and have at least one Windows Server 2008 R2 domain controller in the target domain (which will also require the domain and forest level to be Windows Server 2008 R2). After the migration is complete, you can decommission the Windows Server 2008 R2 domain controller and raise the domain/forest level as required. This process is documented in the Microsoft Support article "ADMT 3.2 and PES 3.1 installation errors on Windows Server 2012."
