I have a network situation I need to run by you experts. I have a Dell server running 2000 and exchange 2000. It is the only AD server in the network. The IT manager wants to purchase a new 2003 server and exchange 2007 and eventualy remove the 2000 AD and exchange server. I am not quite sure of the best procedure to do this. I figured I could upgrade the 2000 server to 2003 then install the new exchange server. Then move thew mailboxes to the new server, but I am not sure this is the clean way to proceed.
