title: Migrate multiple certificate signing to single certificate
body: <p>My org android app is signed with 2 Keystore files. So while doing app signing on Play Store, I am getting the following message</p>
  <pre><code>Your app cannot be enrolled into App Signing because of the following reasons:
  We do not support enrolling apps signed with multiple keys
  </code></pre>
  <p>So, wants to know if there is any way to move from 2 certificate signings to 1 certificate keeping the same app in Play Store</p>
