I am in the process of migrating from exchange 5.5 to 2003. We have a fairly small organization and I probably need to move about 50 mailboxes maximum, probably less. I am also in the process of phasing out old NT servers and getting to a native 2003 environment, but currently am in mixed mode, with Active Directory functioning properly.
I am wondering what the easiest way to migrate the mailboxes is? Active Directory Connector? What about just exporting to PST's from the old 5.5 server, and re importing them on the new server?
