title: From self managed Let's Encrypt to AWS Certificate Manager
body: <p>I have been managing Let's Encrypt's SSL certificates for a domain.</p>
  
  <p>Now I am moving to Amazon API gateway. I will be using the AWS Certificate Manager to generate HTTPS certificates for the root domain and a bunch of subdomains.</p>
  
  <p>If I make the transfer, what happens to my current HTTPS certificate which is associated with my domain. If browsers suddenly start seeing a new HTTPS certificate for a domain, for which they had been getting a different HTTPS certificate until now, would this be a problem?</p>
  
  <p>Also, once I make the shift, what do I do with my current (manually managed) Let's Encrypt certificate? Is there a way to permanently void it?</p>
