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)
Reducing the number of Active Directory domains in your forest in turn reduces or simplifies the following:
Administration requirements for your organization
User and group administration
Implementation of Group Policy
If users are frequently reassigned to locations that are part of different domains, you might also migrate objects between domains on a regular basis. The process for restructuring Active Directory domains within a forest differs from the process for restructuring Active Directory domains between forests. This process requires careful planning and testing.
