We are currently migrating from exchange 2003 to Office 365. We are configured Hybrid so we also have exchange 2010. After the migration is complete I would like to upgrade our active directory functional level so I will need to isolate the exchange 2003 servers and keep them in the event I am asked to do a tape restore (we currently have no data retention policy). I would also like to keep a couple of the exchange 2010 servers in place. With all of that said knowing that the exchange 2010 servers get some of their information from the exchange 2003 servers what would be the best way to accomplish this?
