I am upgrading from 12.1.1.56 to 12.3.2.4165 and I am stopped with a message that the upgrade failed and contact support. I am using the “free” license. I am pretty certain I am good with pre-reqs

    Have you opened a ticket with support yet? Even if you’re on the free license, they will still offer “Best Effort” support for you.

    I find it’s best to create a ticket first, as it may take some time to get a response/solution, then post to the community while you wait.

    I’d recommend making sure all your jobs are disabled or otherwise unscheduled before running the upgrade. If that doesn’t work, stop and disable the Veeam Backup Service and run the installer. The installer should re-enable it automatically when it completes.

    ​@led4 -

    You can’t upgrade to the latest version with any Veeam version earlier than 12.3.2.3617. See the below KB:

    https://www.veeam.com/kb4696

    Scroll down to the Download info to see compatibility:

    ​@led4 Are you using the Patch ISO or the Full ISO?

    Argh thanks

    Yep...no problem. But, if you scroll in that KB just a bit farther down, you’ll see a full ISO you can and should be able to upgrade from, going all the way back to v11a:

     

    Try & download the full ISO and do the upgrade to see if that works for you.

    Let us know how it goes.

    Best.

    So coming back around I have confirmed I have the “Full ISO” and my issue is still occuring.

    I even uninstalled the 12.1 version and tried a fresh install of 12.3 still the same issue. Support closed my ticket ut I will have to re-open.
    Yes I can and did install 12.1 back again with no issue

    Hmm..no answers left ​@led4 . Only suggestion I have, which you prob don’t wanna do...is wipe your system, reinstall Windows and install the latest VBR.

    Yep. That will be the best idea at this point. Before you do that, be sure to get a copy of the Configuration Database Backup and move it off the server.

    Did you collect a support package for your ticket? You don’t actually have to send it to support, you can unzip yourself and see more detailed logs that might give a hint of what went wrong. 

     

    This KB provides a how-to, but if you scroll down, it has some scripts to do it manually, which give away the location of the logs on your server: https://www.veeam.com/kb1832

    Default location is  C:\ProgramData\Veeam\Backup
