title: Changing heroku repo for pre-existing app
body: <p>I created a heroku repo some time ago for my rails app but deleted it because I was never using it. Now I have come to the point where I need to use heroku but I am encountering the following error:</p>
  
  <p><code>!  No such app as furious-mist-2295.</code> which was the old repo name, so it is clearly not pushing to the new stack I created. </p>
  
  <p>This is what I was considering trying, but am concerned about causing unnecessary changes to my git repo.</p>
  
  <p><code>git remote rm origin</code></p>
  
  <p><code>git remote add origin &lt;URL to new heroku app&gt;</code></p>
  
  <p><code>git push -u origin master</code></p>
