Some notes

[caphector]

If the -target-dir isn't set then it fails saying Failed to check disk space:.

At least in my attempt, when I migrated using operation copy it copies WAV files over but I don't see any files of those names in the clips folder. As an example, I see corvus_brachyrhynchos_73p_20241021T092751Z.wav in the DB but:

parrot@birdnet:~/birdnet-go $ find ./data/clips/ -name 'corvus_brachyrhynchos_73p_20241021T092751Z.wav'
parrot@birdnet:~/birdnet-go $

I wanted to merge two birdnet-pi DBs (accidentally created a second a while back; wanted to merge the two into one DB for birdnet-go). As per the other issue I tried to migrate one to a new DB (which worked fine) and then tried the merge function. The merge doesn't seem to have worked, unfortunately. I realize this isn't documented but I wanted to let you know.

parrot@birdnet:~/pi2go/birdnet-pi2go $ -source-db other-birds.db -target-db test.db -source-dir ./BirdSongs/ -target-dir ./clips -operation copy

Total records to process: 30363

[and so on]

The DB size doesn't change between the first and second operations.

Thanks for reporting, I will look into these soon
