You are of course completely correct that SampleLibrary.db is just a Sqlite database. Unfortunately, there’s no super easy way to move an entire sample library. It’s something that’s on my (rather long) list of features to tackle. I will get to it eventually, but probably not in the next month. In theory, if you just delete the database, the plugin should rescan your local directory and recreate the database. It’s not exactly an ideal solution, I know, especially if you have stuff in the database that isn’t in your directory that you don’t want to have blown away.
