title: How to upgrade Android app from official version to test version
body: <p>I currently use the inner sharing of the play console to release new versions to testers. (They have exactly the same package name and signing key.)</p>
  <p>However, the testers responded that they could not upgrade from the official version to the test version, so the app update process could not be tested.</p>
  <p>If I install the app first and open the inner sharing link, the play store displays</p>
  <p><em><strong>&quot;A public version of this app is already installed on this device. Uninstall it and try again&quot;</strong></em></p>
  <p>Is there a way to upgrade directly from the official version to the test version in the play store like installing an apk? (not uninstall app)</p>
  <p>For example, the internal test of the play console may be possible?</p>
  <p>Thanks for your help.</p>
