-Make sure the path of your command prompt on your project path

-Get latest on the source and target branches to avoid this error: “Unable to determine the workspace.”

Instructions
-Shelve your changes
-Open a Visual Studio Command Prompt
-Run the following command

tfpt unshelve /migrate /source:”$/Project/CurrentBranch” /target:”$/Project/NewBranch” “Shelveset Name”

-A shelveset details window will come up, click the Unshelv button.
-Next the Unshelv/Merge window will come up, click the Auto-merg button.
 The command prompt will then start showing the merges into the new branch.
