Perhaps someone has succeeded in doing this so I thought I would ask:)
We have an exchange 2007 server running on win 2008 R2. Many mailboxes.
The server has all roles, client access role, transport, mailbox.
We want to migrate over to One Exchange 2013 server, mailbox by mailbox if possible. Has anyone done this? any step-by-step lists on the web? the new server should co exist perhaps first as mailbox role - and mailflow goes thru the old or?
Appreciate any help,
