Hi <br />
We wish to upgrade our bleeding Exchange server 2003 to 2010 and our DC’s to 2008 R2 on our 3 site locations. <br />
My main concern lies in the correct order to perform the upgrades/migration.<br />
<br />
We have a new SAN up and running, so I would image a fleet of new installation for the DC’s and Exchange followed <br />
by a migration – but in what order?<br />
<br />
Thanks<br />
/David<br />
<br />
Site 1 (HQ-CPH) contains 2 DC running 2003 R2, 1 DC running 2008, 1 Exchange 2003<br />
Site 2 (Branch-STHLM) contains 1 DC running 2008 and fileservers.<br />
Site 3 (Recovery-CPH) contains 1 DC running 2003 R2 and fileservers.

The correct way to upgrade 2003 DC environment to 2008 ( +Exchange 2010)

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Windows Server 2008

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).

Windows Server 2003
