I have an exchange sever 2003 installed and working. I have a new exchange 2007 server on another network. The two networks are completely separate with no connection. How can I take the 2003 mailboxes and put them on the new 2007 system? The move mailbox normal option on 2007 will not be able to see the old 2003 exchange server.
I was hoping I could just copy the database and mount it, but this doesnot seem to work.
