Android - HELP moving away from builtin SQLite to Ormlite

I have an SQLite database that I created in Android that I'm manually managing all the code for to perform my reading and writing. I recently discovered Ormlite. I want to use Ormlite to manage my database from this point forward. The issue is the application is already on the android market and I don't want my user's to lose their data. Is there a way I can tell Ormlite to start managing the already made database? Or is there a standard practice to read all of my data from the old database and write it to a new one?
