Free and paid data stored in database(s)

I am trying to implement a free and paid database version in my android app. In my app I am trying to display Points of Interest (POI) which are stored in a sqlite db.

My scenario is that in the Free version my sqlite will contain 10 POI entries. When a user purchases the premium version from Google Play, another 100 POI entries must be (somehow ?) added to the original sqlite. What is the best way to do this? Does the licensed pkg need to contain another sqlite and then merge the two into one?

Thanks
