title: Git origin to bitbucket
body: <p>I have a project I have cloned from a public repo to my PC which I have tweaked and pushed to Heroku.<br>
  I now wish to push my tweaked code to BitBucket as a backup.</p>
  
  <pre><code>$ git status
  On branch master
  Your branch is ahead of 'origin/master' by 13 commits.
    (use "git push" to publish your local commits)
  
  nothing to commit, working directory clean
  
  $ git remote
  heroku
  origin
  </code></pre>
  
  <p>When I try to add the BitBucket command it errors with:</p>
  
  <pre><code>fatal: remote origin already exists
  </code></pre>
  
  <p>That is, after:</p>
  
  <pre><code>$ git remote add origin git@bitbucket.org:me/myproject.git
  $ git push -u origin --all # pushes up the repo and its refs for the first time
  $ git push origin --tags # pushes up any tags
  </code></pre>
  
  <p>Would I correct in thinking I just have to update "<code>origin</code>" to point to BitBucket instead of the original repo?</p>
