Hi. Did you include spoliers in preview as part of the test? I mean, some apps show a preview of the post when you are scrolling the feed, before opening a post, so my question is if the tests included checking that post with a spolier is hidden both on the preview and when opening the post.

Found a solution, Lemmy Migrate: https://github.com/wescode/lemmy_migrate

The app doesn’t support 2FA so I had to disable 2FA on both accounts, do the migration and then enable 2FA back again.
