title: Git "merge" 2 origins
body: <p>While moving a project between Git repositories I came into a situation when <code>git remote -v</code> gives me:</p>
  
  <pre><code>old-origin https://git.server1(fetch)
  old-origin https://git.server1(push)
  origin https://git.server2(fetch)
  origin https://git.server2(push)
  </code></pre>
  
  <p>And <code>git branch -a</code> gives me only 1 branch under origin (remotes/origin/develop) and all other branches under old-origin (e.g. remotes/old-origin/master). I performed final push being on develop branch.</p>
  
  <p>How can I "merge" 2 origins into one? So that all branches are under origin now.</p>
