    Hello All,

    What level we can do the downgrade for a Media Agent?

    For some reason, we are trying to downgrade one of our Media Agent from SP16 to SP11. The Uninstall of SP16 completed successfully and install of SP11 also completed successfully. After that we able to see Media Agent status ready and Disk Library as well. But when we try to take a backup we faced that error:  Could not connect to the SIDB process at MediaAgent MA.

    Is there a restriction to downgrade Media Agent Service Pack version?

     

    Best Regards.

    Hi Omer 

    It is not possible to roll back a service pack from SP16 to SP11. If you are encountering issue where you are failing to connect to SIDB after upgrade I would check connection or Network Route Rules and see if anything is changed after the upgrade

    If the issue is urgent please engage support to review this

    Regards

    Hi Winston,

    The network connection is fine because all clients are using the same network.

    I did a test and I downgraded from SP16 to SP15. After that, I able to take backup without errors.

    So, the downgrade could it be down to a certain level?

    Hi omer 

    Good to know you got everything working 

    I am assuming you have used the RemoveUpdates.exe from the /Base folder. Although that does work its not recommended as you could cause issue with the Binary applied as part of SP16

    Otherwise did you uninstall SP16 and re-installed the SP15 package, as that could be the other option. 

    However in saying that if you did encounter issue in SP16, opening a support Ticket would still be recommended to drill down and figure out the cause

    Regards

    Hi Winston,

    Thank you for the answers.

    What I want to understand here is how many levels of downgrade can we do for the MA service pack, DDB will work correctly.

     

    Best Regards.

    Hi omer

    There is not specific level or pathway to downgrade a Service Pack, because in most case it is not recommended to downgrade a service back, as the newer binary might not be rolled back properly after upgrade to the later service pack. 

    In scenario such as issue with a specific Service pack, the first approach would be to engage support to determine the next steps.

    Regards
