update trial version database without delete old one
<p>I am implementing an android application and i can't figure out how to solve this problem</p>

<p>I'm trying to deploy an application with an existing SQLite database. </p>

<p>when user install application at the first time , Database will download but as trial version ,  with few records only , there are 10 feature extra than trial version when user select to buy one of them database should updated with new records from server , new records have the same schema of trial version database , so i want to insert purchased records to old database without delete old version and install new one with purchased feature </p>
