title: Moving a TFS 2010 project (history, work items, code, etc.) to TFS 2012
body: <p>We're currently using TFS 2010 for both source control as well as task tracking however the structure of both our projects and project collections leaves quite a bit to be desired.  That being said, we're looking to restructure everything in a more efficient way when we move to TFS 2012.</p>
  
  <p>My question is this, is it possible to move our existing projects into a new TFS 2012 project collection (including work items, tasks, etc.) for legacy/historical purposes?  I'd like to have the current project structure and history available for historical purposes with active development on-going in a different project collection using our new project structure.</p>
  
  <p>Everything I've seen so far suggests that its difficult (or impossible) to move entire projects between collections due to work item numbering, etc.  I've considered detaching our 2010 project collections and re-attaching them  individually in 2012 but I really don't want a whole list of project collections (which is part of our current problem). That then brings me to the challenge of merging project collections or moving a project between collections.</p>
  
  <p>Any suggestions, work-arounds or tips would be greatly appreciated!  Thanks in advance!</p>
