      Hello,

      we are currently trying to migrate a Zarafa 7.2.6 into a Kopano 8.7.9 by using kopano-migration-imap. The problem is, that the gateway.log on the Zarafa Server contains a lot of errors and we are not sure, whether any mail are copied at all:

      By the way, would it be possible to dump the Zarafa database, copy it to the Kopano server and import it, followed by syncing the attachments? I’m a little bit concerned whether the gap between the two versions is to wide.

      Thanks for any feedback and help,

      Stefan

        Yes, that should be no problem. The official statement to this can be found at https://kb.kopano.io/display/WIKI/Migrating+from+ZCP+7.1+or+earlier+to+Kopano+Core+8.5+or+later

        And instead of trying to sync mailboxes via imap the fallback I would use instead would be to go through kopano-backup. For this you can simply point kopano-backup to the http socket of the old one.

        Regards Felix

          Hi Felix,

          thank you for the fast answer.
          Our major problem is, that we have nearly 300 GB in attachments, a 40 GB database, 40 active users currently working on the ofld server and an old piece of hardware with only 32 GB RAM and a Xeon E3 .
          This hardware was good enough approx. eight years ago, but now it’s the bottleneck for this migration.

          Do you agree, that splitting the migration into db and attachements would be the least troublesome way?

          Regards,

          Stefan

            Yes, probably. You only have to account for the time it takes to export and import the database. If you only have a small window where your server can be offline you could speed it up by working with mysql master/slave replication.
