title: Change TFS source control mapping in Visual Studio 2013
body: <p>I have multiple solutions that were previously mapped to a hosted TFS. Their local mapping was defined as well and all the source code was up-to-date locally. I have since discontinued my TFS subscription and started using visualstudio.com as my TFS server.</p>
  
  <p>I went into one of the solutions, deleted the *.vssscc files from the solution and the *.vspscc files from each nested project. When I open the solution in VS 2013, the output window gives me a message saying the the original TFS (unsubscribed now) is not available and that the solution is open offline.</p>
  
  <p>As a result, when I choose the "Change source Control" option, it first asks me to log in to the old TFS whose credentials are no longer valid.</p>
  
  <p>Furthermore, it tells me that the local directory I am trying to map to the new TFS is already mapped to the old TFS. How can I remove this mapping without having access to the old TFS?</p>
