title: How do I merge a Work Item from 1 branch to another in TFS 2008
body: <p>I can't seem to find an easy way of doing this.</p>
  
  <p>We have a trunk, which has a particular set of Changesets checked into a Work Item in TFS. I want to exclusively merge the changesets in this Work Item into another branch.</p>
  
  <p>Surely this can't be difficult?</p>
