Hello, we have three sites that contain exchange 2003 and exchange 2010 servers. Site 1 contains the bulk of the users and the server that was the first exchange 2003 server as well as the first exchange 2010 server. Site 2 and site 3 were all created after site one both for Exchange 2003 and Exchange 2010. At site 2 and site 3, all of the users have been migrated to Exchange 2010 and have been working great. All internet email and public folder comes from site 1. That said, because these are not the first exchange servers, is there anything specific that needs to be done to remove Exchange 2003 from the remotes sites? Any roles that need to be transferred or can I just use add/remove to removed 2003 from those sites?
