Windows Server 2012 R2 backwards compatible? RRS feed

  • Question

  • Hello,

    I was wondering if Windows Server 2012 R2 is backwards compatible with Windows Server 2003. Even though Server 2003 is on its way out it's currently acting as the WSUS. Is it possible to connect Windows Server 2012 R2 to the WSUS (Server 2003) to get it's security updates? 

    -Thanks

  • I have not done any test. However my guess is that WSUS 3.0 SP2 does not see WS2012R2. And this is not a single problem.

    I would use WSUS 4.0 installation on WS2012R2 with the newest version of WSUS and different IIS port until old WSUS is removed.

    IMHO: Supporting expiring troublemaking operating system is too expensive.

  • Hi,

    If you are using WSUS 3.0 SP2 on Windows Server 2003, to let the WSUS support Windows Server 2012 R2, please install the update below:
