I used to write a variety of articles (https://tsoorad.blogspot.com) on technical issues with a smattering of other interests. I have a variety of certifications dating back to Novell CNE and working up through the Microsoft MCP stack to MCITP multiple times. FWIW, I am on my third career - ex-USMC, retired US Army. I have a fancy MBA. The opinions expressed on this blog are mine and mine alone.

OCS 2007 R2 and Server 2008 R2

Originally posted the 17 November 2009, now updated on 20 November 2009

I get this question over and over:  Can we deploy OCS 2007 R2 on Server 2008 R2?

According to the Office Communications Server 2007 R2 Documentation:

  • All domain controllers in the forest where you deploy Office Communications Server run Windows Server 2003 with SP1, Windows Server 2003 R2, or Windows Server 2008.

  • All global catalog servers in the forest where you deploy Office Communications Server run Windows Server 2003 with SP1, Windows Server 2003 R2, or Windows Server 2008.

  • All domains in which you deploy Office Communications Server are raised to a domain functional level of Windows Server 2003 or Windows Server 2008.

  • The forest in which you deploy Office Communications Server is raised to a forest functional level of Windows Server 2003 or Windows Server 2008.

    As of 16 November 2009, Windows Server 2008 R2 is still not supported.

    Having established the “official” facts, I can tell you empirically, OCS R2 on Server 2008 R2 might be OK (emphasis on MIGHT) in a lab, but it is nothing I want to try (again) in anything resembling a production environment.
