Upgrade 2012 -R2 various versions to UR14 RRS feed

  • Question

  • I have a client with around 15 DPM servers to upgrade from various versions of 2012 R2 to UR14. They have been very judiciousabout keeping the system drive clean and thus the install files from the last upgrade ( or the original install) are missing.

    What files from the previous install or upgrade are required to be present for the upgrade to UR14? Is it required that the files that should be in the "\HKCR\Installer\Products\<DPM GUID>\Sourcelist" are present and the correct version?

  • Hello,

    There's no need for the original or previous installation files to successfully update your DPM 2012 R2 to Update Rollup 14.

    As long as nothing has been cleaned/removed from the folder to where DPM was installed, you're good to go.

    Best regards,
    Leon

  • When attempting to upgrade some servers, I get the error : The installation has failed. The installation source for this product does not exist.


    And in the following in the log file, the C:\USers\<username>... folder referenced has long since been deleted as that account no longer exists.

  • Apparently it does seem that DPM 2012 R2 do require the temp folders of the previous install to work...

    So for you to get this working, you would need to restore these files, otherwise I'm afraid there's not many options left, either create a support ticket to Microsoft and they can provide these files, or reinstall DPM.

  • You mentioned your client was running on several different update rollups, which ones?

    I could try to install DPM 2012 R2 in my lab to the equivalent version and check for the files that you're missing.

  • 4.2.1417.0 2012 R2 UP 9
    4.2.1473.0 2012 R2 UP 10

    4.2.1553.0 2012 R2 UP 11
    4.2.1589.0

    2012 R2 Up 12

    I was not able to find source media old enough to install to steal the files for anything older than UR12, as I recall.

  • Okay, so all of the above mentioned versions cannot be upgraded and receive the same error as in your initial post? Are all of those servers cleaned up?

    So you need the source files for Update Rollup 8 or earlier?

  • Correct. Assuming that the install actually checks for the correct version of the previous source file.
    Tuesday, September 3, 2019 12:59 PM
  • Okay, I'll try to get the source files and upload them to a shared link for you, meanwhile you should probably make sure that the paths of the source files exist on the servers, they can be found in the Windows Registry you mentioned earlier.

  • Did some testing in my lab and it appears that no files are extracted to C:\Users\<username>\AppData\Local\Temp\...

    When you run the Update Rollup executable (Detectoid for System Center 2012 R2 - Data Protection Manager Server-all-dataprotectionmanager2012r2-kbXXXXXXX) it actually creates a temporary folder directly under C:\, drive, the name will be a random generated GUID, as you also can see from your log:

    Calling process: c:\cc06862c24b9ed01628f1a60b4\RunDpmPatch.exe

    So I'm wondering the following:

    • Are you running the setup as an administrator?
    • Are there any restrictions on the C-drive?
    • Any antivirus software that may be blocking the setup?
    • Have you tried running the executable from an elevated Command Prompt?

    I've extracted the Update Rollup 8 files and zipped them, you can access it over here:

  • Yes, running as admin.

    No drive restrictions.

    A/V is present but disabled.

    Yes, ran from elevated command prompt.

    I can't speak to how previous updates were applied.

    It appears from the log that it is looking for msdpm.msi, which is not extracted in the download. I think I am going to have to install a version that is less than UR8, apply UR8, and then seek out that source path.

  • A disabled antivirus can still block (I have experienced this), although I don't believe it to be the case now.

    What actually happens when you run the Update Rollup installer?

  • I get an error dialogue stating that previous install can't be found.
    Wednesday, September 4, 2019 7:42 PM
  • Very odd indeed...

    It's difficult to know exactly how these installers behave and what they do require, if your client has a support agreement with Microsoft, it would probably be better to reach out to Microsoft.

    Another workaround is simply reinstalling DPM, with retain database option, the DPM installation doesn't take long, this would also ensure you don't miss any files.

  • I do not have the original install .iso. I would be installing a newer version.

    I thought DPM 2012 R2 was EOL for regular support?

    Thursday, September 5, 2019 1:40 PM
  • Where was the original installation media obtained from? VLSC/MSDN? It should still be there, or then the client can contact the reseller for the installation media.

    The mainstream support is no more, but the extended support is until 7/12/2022.
