So you want to copy a work item (WI)? Well TFS does indeed have a copy command via the UI which will create a new work item based upon a certain type.

The issue here is that this could be a timely process based upon the number of copies that need to be made. Not to mention the fact that this is a one off process so bulk copying, say 200 WI's (i.e. User Stories) is just not possible.

That said, with a little bit of code and using the Visual Studio Team Foundation Server SDK, it’s possible to harness this functionality to copy a WI as opposed to using the UI. While this code only converts one WI (i.e. User Story -> Task), it’s not a stretch to customize it to iterate through a list of WI’s. As always, a word of caution - use this code at your own risk as using the TFS namespaces directly could severely damage your backlog.
