I'm looking for a step-by-step guide on how to upgrade an Exchange 2003 server to Exchange 2010.
Ok, it's not exactly an upgrade. I will install Exchange 2010 onto a Win2008r2 server. How do I move the mailboxes and settings? What do I have to change in AD? ...
AD is running in 2003 native mode, I already have added a 2008r2 domain controller.
