My company has a Windows Server 2008 running a virtual server of Windows Server 2003 (with Exchange 2003). We want to upgrade to Exchange 2010. Since I need to know what steps to take to migrate everything from the virtual server running Server 2003 and Exchange 2003, to the physical server running Server 2008 and Exchange 2010. This includes all the AD stuff and all the Exchange stuff.
Software/Hardware used: Server 2008, Exchange 2010, Server 2003, Exchange 2003

AD Portion: (1st phase)
Lets assume you have this virtual 2003 Server as a DC and you want to make the 2008 server a DC. You will need to perform some active directory prepartion (schema changes, etc.) to accept a 2008 DC. Once that is done, and both DCs see each other, you may want to consider migrating all the FSMO roles over to the new DC.

Exchange portion: (2nd phase)
Your best option would be to ADD the Exchange 2010 to your Exchange Organization and then migrate mailboxes from the 2003 Server over to the 2010. In order to add the 2010 Exchange server, you will need to prepare AD with Once that is completed, you can eventually after a thorough testing, you can decommission the old 2003 Exchange.
