title: Is it possible to move custom domain from one web app to another?
body: <p>I have a custom domain www.abc.com configured for web app webapp-a, and I'd like to transfer it to webapp-b without downtime.</p>
  
  <p>If I try to add the domain to webapp-b, I am getting</p>
  
  <blockquote>
    <p>The host name www.abc.com is already assigned to another Azure website: webapp-a</p>
  </blockquote>
  
  <p>It there a way to let webapp-a continues to serve the requests, until the DNS cache expires?</p>
  
  <p>Edit: The domain has IP based SSL binding, and the DNS is caching the virtual IP.</p>
