      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…

                @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.)

                      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.

                      Regards Felix
