09/20/2023, 3:02 PMthe only way I know how to do this is via manually running schema commands that undo the ups, which aren’t really specified so would have to look at what ups ran and reverse engineer the downs from that

09/20/2023, 3:03 PMThe only safe way to try to undo the migration would be to create an isolated backup of airbyte’s postgres instance, run the sql to undo the changes (you would have to go look at the migrations to see what got applied) and try to run 0.50.21 against it afterward. If that worked after some testing you could do the same on your production db
