Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2

Applies to: Active Directory Migration Tool 3.2 (ADMT 3.2)

The Active Directory Migration Tool (ADMT) changes global groups to universal groups when you migrate them from the source domain to the target domain. The change occurs automatically because global groups can contain only members of their own domain. Therefore, they cannot continue to be global groups when they are migrated to another domain until the group members are migrated. ADMT changes the universal groups back to global groups when the last member of the group is migrated to the target domain. Because universal groups replicate their membership to the global catalog, it is important to verify that the universal groups correctly changed back to global groups.

Use the Active Directory Users and Computers snap-in to verify that universal groups migrated successfully. If you changed domain local groups into universal groups manually, make sure that you switch them back to domain local groups when all resources have been migrated.
