  • Question

  • Hi All,

    I Have DPM 2012 RTM VM running on Windows server 2008 R2. I would like to

    1) upgrade DPM 2012 to DPM 2012 R2

    2) In place upgrade of server 2008 R2 to Server 2012 R2

    3) Also VM running on windows server 208 R2 host, will 2008 R2 host server will support server 2012 R2 VM ?

    I found few links regarding DPM 2012 RTM to 2012 SP1 upgrade but still requires neat steps to upgrade to 2012 R2.

    Any help would be highly appreciated.

  • Hi Ashwin,

    For the time being running a 2012 R2 Guest on a 2008 R2 Host is unsupported as found at:

    http://technet.microsoft.com/en-us/library/cc794868(WS.10).aspx

    There is an hotfix for 2012 Guests but there is no information given if this is also applicable, and supported by Microsoft for 2012 R2 Guests.

    If you have no intention to upgrade the Hyper-V host to 2012 or 2012 R2 I would advise you to stay at 2008 R2 as Guest as DPM 2012 R2 can reside on this OS as found at:

    http://technet.microsoft.com/en-us/library/hh758176.aspx

    If you have intentions to upgrade the Hyper-V host to 2012 or 2012 R2 I would advise you to:

    - Upgrade DPM to 2012 R2 with the proper steps.
    - Backup the database
    - Uninstall DPM and retain the data.
    - Do a clean install of 2012 R2, keeping the same computer name and domain as before.
    - Patch the OS
    - Install DPM 2012 R2.
    - Restore the database.

    I always prefer to do a clean install of the OS, but keep in mind that this is my own personal experience and it’s up to you how you want to do it.

    A blogpost on how to do this for Server 2012 is found at:
    http://www.andyheywood.co.uk/archive/2013/03/99/

    You can follow the upgrade path for the DPM environment at the first blogpost that Eugene posted that is written by Kevin.

    Keep in mind that you might have to lift your SQL Server to at least SQL 2008 R2 SP2 or SQL 2012 SP1.

    To keep the answer short:
    First upgrade DPM to the latest version using the above posts.
    Then take a decision on if you want to do an In-Place upgrade, clean install of the operating system or stay with 2008 R2.

  • Thanks Eugene for your reply.

    Would you please provide more details especially mentioning sequence which contains both OS and DPM upgrade. As which needs to be done first and in what order.

    1) Upgrade DPM 2012 to DPM 2012 R2 (you can protect Windows 2008/R2, 2012/R2, NOT 2003)

    2) Upgrade (Recommend clean installation  ) windows server 2008 R2 host to windows server 2012 R2 (DPM 2012 R2 officially supported)

    3) Upgrade OS DPM Windows Server 2008 R2 to Server 2012 R2

    - Backup the database
    - Uninstall DPM and retain the data.
    - Do a clean install of 2012 R2, keeping the same computer name and domain as before.
    - Patch the OS
    - Install DPM 2012 R2.
    - Restore the database.

    (agree with Tobias M. Nilsson)


    Have a nice day !!!
