I did a little more digging here and found this which tells you how to modify the SQLite database. Something necessary if you’re switching between Windows and Linux systems like Unraid because they use different path separators (“/“, ”\”).
I decided to not do a clean docker reinstall and deleted the blobs and the generated folders. I then replaced them with the ones from my backup and started up the Stash docker. It prompted me to do a schema migration at startup which was successfully completed. I only took a quick look but it seems to have been successful. I intentionally didn’t replace any other folders to simplify things and since this isn’t meant to be permanent. I’ll edit this if there’s any problems.
