title: Unshelve to another branch
body: <p><br>
  I'm trying to unpack my changes to the another branch using TFS Power Tools. I'm trying to execute command</p>
  
  <pre><code>tfpt unshelve /migrate "NuGet Build" "/source:$/ProjectName/Main/Source" "/target:$/ProjectName/Main/Source-NuGet"
  </code></pre>
  
  <p>But it returns message <code>'tfpt : Unable to determine the workspace'</code>.</p>
  
  <p>I'm running command from the directory that mapped to this project. Moreover I've tried to 
  use <code>tf workspaces /s:http://our-tfs</code>.</p>
  
  <p>Does anyone know how to solve this problem?<br></p>
