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)

  • Perform regular backups of domain controllers in both the source and target domains throughout the course of the migrations. If you are migrating computers that contain file shares to perform security translation, we recommend that you also back up those computers throughout the migration.

  • Verify that workstations and member servers have restarted immediately after you join them to the target domain. The Active Directory Migration Tool (ADMT) automates the restart of workstations and member servers, but you use the Minutes before computers restart after wizard completion option in the Computer Migration Wizard to select the amount of time that passes before the computer is restarted. Computers that do not restart after migration are in an indeterminate state.

  • Communicate to end users that their computers must be connected to the network at the time that their computer is scheduled to be migrated.
