Kopano Core Rollback



  • Hello,

    because of several bugs in the current release I want a rollback of a previous version.
    How do I do that?

    Thanks

    Regards

    Hi,

    If your going back not to far it should be enough to install the older kopano-core release above the newer one and use the ignore database switch to start

    service zarafa-server start --ignore-database-version-conflict

    rg

  • Hi Christian,

    unfortunately I must go from 8.4.0-693 to 8.4.0-35 beause i have not stored a newer version,
    and Kopano does not pusblished older versions.

    When I try to use the "ingnore database switch " the server does not start.

    Regards…



  • Also having trouble with the rollback. Also tried to set the option /etc/default/kopano



  • @schmidt

    Ok I think that version should be ok I meant with older version 8.2 or earlier

    what does the server.log show on trying to start kopano-core

    rg

  • @externa1 In my case the options seems to be ignored. The server is complaining about newer database version.



  • Hi,

    I delete the revision information from the database.
    Then the kopano server start without an error.

    Insert Code Here
    ```DELETE from versions WHERE databaserevision=66 AND revision=693;


  • @schmidt Thank you! Now I also have a way to understand if a rollback causes problems. I was not aware of that there is a whole history of database revisions.

    (Rollback worked. Back to normal operations. Waiting for a more stable versions with patience.)


  • Kopano

    as long as the database revision stays the same a rollback is always possible and quite painless.

    Personally I would also always remove the failed upgrade from the versions table, but if the downgrade is only for a quick test starting kopano-server with the --ignore-database-version-conflict is of course also possible.
