title: Android Realm migrating from 1.x to 2.x
body: <p>We're trying to migrate Realm from 1.x to a 2.x version. Do we need to provide migration in this case? We would like to keep the data obviously, but I think Realm deletes it if you update the app now. We havent released the 2.x version yet so now we need to deal with migration.</p>
