Exchange-Specific Steps: Prepare a Domain that Contains Exchange
Applies To: Windows Server 2008, Windows Server 2008 R2
You can use this procedure to prepare a domain that contains Exchange for a domain rename operation. The Windows Server 2008 domain rename operation is not supported in an Active Directory forest that contains Exchange Server 2003, Exchange Server 2003 Service Pack 2 (SP2), Exchange Server 2007, or Exchange Server 2007 Service Pack 1 (SP1).
If your forest contains Exchange 2003 Service Pack 1 (SP1) servers, you can run the Windows Server 2008 domain rename operation, but you must also use the Exchange Domain Rename Fix-up Tool to update Exchange attributes. For more information, see Microsoft Exchange Server Domain Rename Fixup (XDR-Fixup) https://go.microsoft.com/fwlink/?LinkID=122982). This document describes preliminary steps and instructions for running the Exchange Domain Rename Fix-up Tool. As part of the preliminary steps, you must move Exchange off all domain controllers and discontinue Exchange configuration changes.
