Hello, I am about to start testing a domain rename of our environment, thankfully our domain only consists of two domain controllers. However our domain is Windows 2008 functional level, which I believe domain rename is support with Exchange 2003. Has anyone successfully renamed a Windows 2008 functional level domain with Microsoft Exchange 2003? My problem is that if I use a control station to do the rename, I cannot use XDR-Fixup tool with Microsoft Windows 2008 server. Any advice would be gratefully received. Thanks, Mark

Hi AFAIK domain rename is not supported I want to recommend you doing a cross-forest migration instead, use ADMT and cross forest move the mailboxes If you don't want to use the native tools check for Quest's QMM: http://www.quest.com/migration-manager-for-exchange/Jonas Andersson | Microsoft Community Contributor Award 2011 | MCITP: EMA 2007/2010 | Blog: http://www.testlabs.se/blog | Follow me on twitter: jonand82
