  • Hyper-V Server 2008 R2 SP1 can be upgraded to Hyper-V Server 2012.

    Windows Server 2008 R2 SP1 (Core Installation) with Hyper-V can be upgraded to Windows Server 2012 with Hyper-V.

    Do you have Server with the Hyper-V Role, or Hyper-V Server?  They are distinct SKU's with unique paths.

    What is your error?

  • I have Hyper-V 2008 Server OS which i have to upgrade to Hyper-V 2012 OS.

    Error ""Hyper-V Server (Server Core) cannot be upgraded to Hyper-V Server 2012. You can choose to install a new copy of Hyper-V Server 2012 instead, but this is different from an upgrade, and does not keep your files, settings, and programs.""

  • Brian Thanks for information, but that thread doesn't talk of about resolution of issue i am having.

  • Then what is the issue that you think you are having?

    The errors match and the resolution is the same.  You have to do a clean Install and Hyper-V will "Import" the old VMs without them being exported.

    You just have to have your VMs on a volume other than C:\

  • I have couple of other application running on my HOST that's why i am preferring OS upgrade over clean install. Hence Clean install is my last option. I am just wondering why OS upgrade doesn't work with Hyper-V 2008 R2 SP1 to Hyper-V 2012 (both are core installation).

  • If you have other applications running on your Host, then are you running Hyper-V Server or are you running Windows Server with Hyper-V?

    The only things I can think you would have on Hyper-V Server are AV or backup agents.

    Some other folks and myself recently helped another individual, and there was a lot of confusion about the term "core installation".

    You will find that we only refer to a Core installation if it is Windows Server with Hyper-V installed with the Core option.  The free Hyper-V Server SKU is not a "core" installation, it is actually stripped back much leaner.

    And the upgrade options are different depending on what is truly installed.

    wmic will clarify:  http://www.petri.co.il/quickly-find-your-windows-version-and-architecture-info.htm#

    or, at a command prompt, type wmic.  When in wmic type OS for the verbose detail.
