title: Pushing an update to Google Play that will replace the existing app
body: <p>I have an app that is currently on the Play Store, and I would like to publish an update that will replace the existing app with another app that is an improved version of the old one. They were developed separately, so the two apps are way different, although they serve all the same purposes. </p>
  
  <p>What needs to be the same in the new version and the old version for me to be able to publish is as an update instead of a brand new app?</p>
