What is the best way to upgrade from Exchange 5.5? Should we migrate to Exchange 2000 first, and then to Exchange 2003? I have heard horror stories about a straight migration path from Exchange 5.5 directly to Exchange 2003.
Some users have more than 2 GB on the Exchange 5.5 database. Is it possible to set up multiple storage groups on Exchange 5.5 as in Exchange 2003?
