@jk Thanks for the write up! Indeed, the migration is a bit rough because Wallabag had made a 2.3.8 release back in May 2019. Then a 2.4 release came up after 1.5 years but this wasn't "upgrading" cleanly and had many migration issues. In fact, there are still migration issues pending upstream like 5197, 4820, 4979, 4821. We thus decided it's best to start "afresh" because it doesn't seem like the migration issues will be fixed any time soon.
