title: How can I issue a certificate after I've moved to a new cluster?
body: <p>I setup up a prototype cluster in Azure Kubernetes Service to test the ability to configure HTTPS ingress with cert-manager. I was able to make everything work, now I'm ready to setup my production environment.</p>
  
  <p>The problem is I used the sub domain name I needed (sub.domain.com) on the prototype and now I can't seem to make Let's Encrypt give a certificate to the production cluster.</p>
  
  <p>I'm still very new to Kubernetes and I can't seem to find a way to export or move the certificate from one to the other.</p>
  
  <p><strong>Update:</strong></p>
  
  <p>It appears that the solution provided below would have worked, but it came down to needing to suspend/turnoff the prototype's virtual machine. Within a couple minutes the production environment picked up the certificate.</p>
