Downgrade Management Pack RRS feed

  • Question

  • Hello,

    We are running SCOM 2012 R2 and want to downgrade the Windows Server Operating System Library from 10.1.0.0 to 10.0.8.0.

    Is the following process the best way to do this?

    1.  Export unsealed mp's with overrides associated with the Windows Server Operating System Library.

    2.  Delete unsealed mp's with overrides associated with the Windows Server Operating System Library.

    3.  Delete Windows Server Operating System Library 10.1.0.0.

    4.  Import Windows Server Operating System Library from 10.0.8.0.

    5.  Import unsealed mp's with overrides associated with the Windows Server Operating System Library.

    I understand the 10.1.0.0 mp is not compatible with SCOM 2012 and I am seeing several discovery issues and that's why I want to downgrade. 

    Any tips/advice would be appreciated!

    Thank you

    --David

  • Hi David,

    There's no official way of doing a "downgrade of management packs", but your steps seem to be correct and as far as I know it's the only way to do this and it should be fully supported.

    I would also recommend using the SCOM Self Maintenance Management Pack, this can for example back up your management packs for you which could save you some time.

    OpsMgr Self Maintenance Management Pack 2.5.0.0 

    Best regards,
    Leon

  • Hi,

    For this query, per my understanding, the general process seems to be working, however, it may be more complex. 

    We can only delete a MP if it not referenced by other MPs, for example, the MP we created to store the custom overrides, which only reference other MPs and not be referenced.

    the Windows Server Operating System Library MP is the core MP and is referenced by other MPs (those MPs may possibly be referenced by other MPs). To remove this MP, we may need to remove the entire MP dependency tree manually and import them again.



    this happens with both GUI and PowerShell cmdlet

    Get-scommanagementpack | where {$_.name -like '*windows.server.library*'} | remove-scommanagmentpack

    Hope the above information helps.

    Regards,

    Alex Zhu

  • Thank you Alex and all for your support!  I was able to manually "walk" the dependency tree and delete the necessary management packs, import the sealed management packs, updated the non-sealed management packs and import successfully.

    I am still not seeing the disk show up from the Server 2016 logical disk discovery but that is a related but separate issue.


    Thank you again for the assistance!
