Pedro Okawa' solution is correct, but you need to write your "UpgradeHelper" to extend "OpenHelper" because DaoMaster is overwritten each time you re-generate DAO code.

Example:

public class UpgradeHelper extends DaoMaster.OpenHelper {

public UpgradeHelper(Context context, String name, SQLiteDatabase.CursorFactory factory) {
    super(context, name, factory);
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

    Log.i("greenDAO", "Upgrading schema from version " + oldVersion + " to " + newVersion + " by migrating all tables data");

    MigrationHelper.getInstance().migrate(db,
            UserDao.class,
            ItemDao.class,
            AnotherClassToGenerateDao.class);
}

}
