Is it possible to run Exchange 5.5 and Exchange 2003 at the same time?
Posted on 2008-10-07
I have a server running Exchange 5.5. I want to phase out Exchange 5.5 asap.
I would like to install Exchange 2003 on a separate server and run both versions of Exchange at the same time.
I would hope this would allow me to move mailboxes one at a time to the Exchange 2003 server at my leisure. When all mailboxes are finally all on the Exchange 2003 server, I would then eliminate the Exchange 5.5 server.
This would mean both the Exchange 5.5 server and the Exchange 2003 server would be running at the same time for awhile.
Is this possible?
(Both servers' OS = Windows 2000 Server.)
