title: How good are the tools to migrate to and from Team System?
body: <p>I was wondering if anyone tried migrating between TS and SVN/CC. 
  What I mean by migrating is importing and exporting the repository between source control systems without losing the history.</p>
  
  <p>How good are the tools to migrate to and from VSTS? </p>
  
  <p>I am also interested in knowing any opinion regarding using Team System from users of SVN and continuous integration.</p>
  
  <p>EDIT:
  Assume I need the history, otherwise why use a SCM?</p>
