Remove Exchange 5.5 servers from a mixed mode Exchange environment
Exchange Server 5.5 and Exchange Server 2003 are running in mixed mode. One of our three Active Directory (AD) sites is in a separate forest and we would like to create a single forest to remove all of the Exchange 5.5 servers, which are only used for global address list (GAL) replications. How can we accomplish this?
We have a single Exchange organization and three AD sites connected through a Multiprotocol Label Switching (MPLS) cloud.
