title: Upgrade realm in an Android project
body: <p>I'm currently running Realm Version 0.82.0 in one of my Android projects. I didn't touch Realm for quite some time, until I recently noticed that they went up until version 2.0.2 in the meantime. I would like to upgrade my version of Realm, unfortunately, I don't know if the upgrade from my old version to the current release will be working or breaking my code. </p>
  
  <p>I'm especially concerned of migrations, since the API for migrations seemed to have changed a bit since my code, and I'm unsure if my migrations will break if I just update my version. Unfortunately, there is no documentation about upgrading Realm version available on their webpage.</p>
  
  <p>Does anyone have any experience with upgrading Realm, especiall a version increase over two major versions?</p>
