Windows Server 2008 R2 Upgrade Paths

Friday, October 28, 2011

Let me start by saying that I am definitely not a fan of "in-place" upgrades. However, there are scenarios that you simply must choose this option. Before summarizing what is supported, its a good idea to go over what is not supported.

Unsupported Upgrade Scenarios

  • Windows 9x, Windows Millennium, Windows XP, Windows Vista Editions, or Windows 7
  • Windows NT Server 4.0
  • Windows 2000 Server
  • Windows Server 2003 (RTM & SP1), Windows Server 2003 Web
  • Windows Server 2003 for Itanium-based Systems
  • Windows Server 2008 R2 (M3 or Beta)
  • Windows Server 2008/2008 R2 for Itanium-based Systems
  • Cross-architecture in-place upgrades (x86 --> x64)
  • Cross-language in-place upgrades
  • Cross-edition upgrades (Foundation --> Datacenter)
  • Cross-build type in-place upgrades
