title: Copy/fork a git repo on github into same organization
body: <p>I have a repo on github that contains a web application that's deployed to two different domains.  The application has slight logic forks here and there to behave differently depending on which domain it's deployed to.</p>
  
  <p>It's come to the point to where I want to split it into two separate repos, one for each domain.</p>
  
  <p>Github won't let me fork it into the same organization.  Searching for "git duplicate repo" suggests I should bare clone and mirror push it, but that seems to be for keeping both repos in sync, which I don't want to do.</p>
  
  <p>What's the best way to go about this?  I'd like to preserve the old commit history in the new copy if possible.</p>
