title: Update the APNs certificate and change the Apple ID
body: <p>Our APNs certificate is about to expire as it shows on FireBase console. I need to renew it. I have 2 main issues:</p>
  <ol>
  <li>I visited Apple's website:</li>
  </ol>
  <pre><code>https://developer.apple.com/account/resources/certificates/download/{some code}
  </code></pre>
  <p>where <code>{some code}</code> is some kind of a an id, presumably.
  I do not see a &quot;renew&quot; just &quot;revoke&quot; and &quot;download&quot;:

  Checked with the original Apple ID that created the certificate as well as another one.</p>
  <ol start="2">
  <li>The guy who originally created the certificate is leaving, so I need to have the option to renew it with a different Apple ID in the future.</li>
  </ol>
  <p>As I understand, if I revoke the certificate and create a new one, that would stop the push notifications and all devices would have to &quot;enroll again&quot;. What does that mean exactly? Would that mean sending a new update? What would have to change on the client/server side?</p>
