title: Migrate tfs server
body: <p>I have been searching for a tool to assist with migrating a tfs server and cannot find one! Is it a backup and restore of a database? Has anyone done this before?</p>
  
  <p>My requirements are: we have tfs server A and tfs server B. Both on separate boxes and databases and different domains, as part of consolidation tfs server B will be decommissioned. Moving Code is easy as I can check in a new branch no issues but I don't want to lose all the work items. I don't mind if the work items are assigned to a new single user I just don't want to loose them...</p>
  
  <p>Both 2012. Any ideas thanks!</p>
