ownCloud 10 is EOL and for sciebo we needed to make a difficult choice on how to continue for the upcoming years. As a result, we are now in the process of migrating 230k users across approximately 45 instances from ownCloud 10 to Nextcloud.

We will report on: - why we chose to continue our own helm chart - fixes and features we needed before making the move - first roadblocks and how we've overcome them - current progress - hopefully no horror stories - streamlining database operations of 45 galera clusters - evolution of our application landscape
