Hi there, I have a question regarding the installation/migration of an Exchange 2000 to Exchange 2007. The Exchange is totay running at a SBS (Small Business Server 2000), but I would like to move the Exchange to a new server, running 2003 R2. The only issue that I can see, is that our present Domain Controllor, won't be able to make it? or will I be able to make some sort of replication between our existing Active Directory, and the one lying below on the 2003 server, running the Exchange 2007? Regards Jon
