I have a new server and a license for Exchange 2010 to install for a 50 user company with ~25GB of mail.
They previously used Exchange 2003 on 2 servers, 1 of which has been removed in the meantime. After Exchange 2003 they moved to MDaemon but now want to move to Exchange 2010 on the new server.
The old Exchange installation is unused but running on the 1 remaining server, do I need to upgrade/migrate this existing Exchange 2003 organisation?
Can I delete Exchange 2003 and create a new 2010 installation from scratch? As Exchange and Active Directory are linked at the hip I don't know if this is possible.
P.S. Is there any better way of transferring the data from Mdaemon than exporting from Outlook to a PST?
