title: tf workspace collection url changed
body: <p>I migrated TFS from an old server "<em>OLDMACHINE</em>" to a newone "<em>NEWMACHINE</em>". TFS is shutted down on <em>OLDMACHINE</em>. Now I want to update my different URLs on developpers computers.</p>
  
  <p>For my git clones, the command is :</p>
  
  <pre><code>git remote set-url origin https://NEWMACHINE/...
  </code></pre>
  
  <p>I don't find the corresponding command with tf workspaces. I've search in the Visual Studio's window <em>Workspaces...</em>, but I can't open it anymore because my old TFS is down.</p>
  
  <p>The next command show me my workspaces :</p>
  
  <pre><code>tf workspaces
  </code></pre>
  
  <p>Is it possible to update the URL with</p>
  
  <pre><code>tf workspace ?
  </code></pre>
  
  <p>There are many documentations about renaming computer, moved folder, username, but I didn't find any in my direction.</p>
  
  <p><strong>EDIT :</strong>
  I found this key in regedit, with subkeys. I want to give it a try, has anyone ever done this manipulation?</p>
