If you look for a way to export and import your area and/or iteration structure the Team Foundation Object Model (TFOM) is your friend.
However it’s only your friend if you know where to look for.
While the export works perfectly using the WorkItemStore, the import is only possible through the ICommonStructureService (and could be used for export as well).
At the bottom you can download the source code of TFS Area Import/Export Tool.
It saves your area and/or iteration structure into a text file and lets you import it into another project (even on another Team Foundation Server).
Feedback is appreciated.
