It's just a SQLite database that is used to store all of the data in the library, so a simple query can transfer all of the data fairly quickly. If you expose the database, copy it to your PC, and then use a program to execute the queries to update the appropriate tables, it shouldn't take long at all to do what you desire. I can provide the query for you too if you'd like.
