This looks interesting. Can I use it to back up photos from one (old) photo library, and restore them into another (newer) one?

Yes — that’s exactly what it’s designed for. You can back up photos from one Photos library and later restore them into a different Photos library. The restore process recreates the items in the target library using the data stored in the backup.

Thanks. I'll give it a go
