After upgrading dpm to 2012SP1, is an In-Place OS Upgrade from Server 2008R2 SP1 to 2012 supported? RRS feed

  • Question

  • I understand that DPM 2012 SP1 requires that it be running on Server 2012 in order to get some of the new features.  Looking over the upgrade instructions on technet, it seems to say that we should upgrade DPM to SP1 before upgrading the OS.  It doesn't explicitly say that an in-place OS upgrade is supported though, after the DPM upgrade is finished.  

    Is it supported to upgrade the Server OS in place after DPM has been updated to 2012 SP1?

  • Not sure about the official support guideline but to avoid upgrades i would

    Upgrade DPM to 2012 SP1

    Backup DB Database

    Reinstall OS DPM restore database and sync

    But i know that hans earlier today did a inplace upgrade without issues but remove 3rd party drivers/teaming before a upgrade

  • Thanks, that's exactly what I was looking for. 

    For anyone else who might come across this thread, this is mike's post from the thread FlemmingRiis linked above:


    Yes, Server 2008 (R2) Hyper-V does not support the .vhdx format.

    The correct upgrade steps would be.

    1) Backup the DPM 2012 SP1 DPM database.
    2) Un-install DPM 2012 SP1 - maintain replica data.
    3) Upgrade the Server 2008 O.S> to Server 2012 O.S.  Make sure the DPM storage pool disks are imported.
    4) Install DPM 2012 Sp1
    5) Restore DPM 2012 Sp1 Database using Dpmsync -restoreDB ...
    6) Run DPMSync -Sync to make new mountpoints.
    7) Run CC to get all datasources green.
