    Windows Server 2003 and Windows Server 2003 R2 can both be upgraded in-place to Windows Server 2008, as long as you keep the following in mind:

    • The Windows Server 2003 patchlevel should be at least Service Pack 1
    • You can’t upgrade across architectures (x86, x64 & Itanium)
    • Standard Edition can be upgraded to both Standard and Enterprise Edition
      • Enterprise Edition can be upgraded to Enterprise Edition only
      • Datacenter Edition can be upgraded to Datacenter Edition only

    This might be your preferred option when:

    • Your Active Directory Domain Controllers can still last three to five years economically and technically)

    • You worked hard to get your Active Directory in the shape it’s in.

    • Your servers are in tip-top shape.
