I will lay out which versions of Exchange are supported on which OS version and also which domain controller version they can use. I will detail the supported methods to move from Exchange 2007 on Window Server 2003, to Exchange 2007 on Windows Server 2008 and finally I will cover the prerequisites needed, before showing the actual install. Note: At this time, neither Windows Server 2008 nor Exchange Server 2007 SP1 have released to manufacturing. As I am therefore working with beta code, certain elements of what follows (in particular the screenshots, may change before the final version. Introduction It is nearly a year after the release of Exchange 2007 and many of us now have complete Exchange 2007 implementations. I guess that means we are looking for something new to do! If this is the case then you won’t be disappointed, as very soon we will be presented with the new challenge of moving our existing Exchange 2007 systems onto Windows Server 2008. Uninstall Exchange Server 2007![]() Force Uninstall Exchange Server 2007Table 1 lists the various supported scenarios for Exchange and OS versions. Exchange Version Server OS Supported for Installation Exchange 2003 Windows 2000 Server SP4 Windows Server 2003 (All SP levels and R2) Exchange 2007 RTM Windows Server 2003 SP1 + SP2 (inc R2) Exchange 2007 SP1 Windows Server 2003 SP1 + SP2 (inc R2) Windows Server 2008 RTM Table 1: Exchange/OS versions supported for install The first thing to note is that Exchange 2007 RTM is not supported on Windows Server 2008. To install Exchange 2007 on Server 2008 you must run Exchange 2007 SP1. This service pack, as many of you may know, is a little different from previous service packs in that it is a complete installation of Exchange. Effectively SP1 is RTM with the SP1 code slipstreamed into it. Having established that Exchange 2007 SP1 is required to install on Server 2008, what other considerations are there? Probably the biggest consideration is Active Directory. Table 2 sets out the different Domain Controller versions supported by different versions of Exchange. Exchange Version Domain Controller OS Supported Exchange 2003 Windows 2000 Server SP4 Windows Server 2003 (All SP levels and R2) Windows Server 2008 RTM Exchange 2007 RTM Windows Server 2003 SP1 + SP2 (inc R2) Windows Server 2008 RTM Exchange 2007 SP1 Windows Server 2003 SP1 + SP2 (inc R2) Windows Server 2008 RTM Table 2: The Exchange/Domain Controller support matrix One new Active Directory feature of Windows Server 2008 which I haven’t mentioned is Read Only (RODC) (and Global Catalog servers). These are servers which do not hold a writable copy of the AD and also do not hold account passwords. They are most likely to be used in branch office scenarios to prevent security breaches either intentional or accidental. Exchange 2007 DownloadSo how do these RODCs affect Exchange? Simply put, Exchange doesn’t use them! When left to automatically associate with a domain controller (or global catalog server) Exchange will ignore the RODC or ROGC. The important thing for administrators to remember is not to manually set Exchange to work with a RODC as things simply will not work correctly.
