We are planning a rename of our domain. All of our DC's are Windows 2003 Enterprise servers. The forest functional level is 2003. We have an Exchange 2007 rollup 5 on our domain. I understand that if I had Exchange 2003 then I would need to run xdr-fixup to fix the Exchange attributes. Is this the case with Exchange 2007? Is there anything special I need to do for this Exchange server?
