Running the "Dog Food" stats on your new TFS 2010 server is a good way to see if the upgrade was successful. You should check the new values against the stats you noted down from your TFS 2008 server.
- On TFS2010, run the DogFoodStats queries and save the results

- Compare the numbers are the same
- Note: Number will differ slightly (usually increases as TFS2010 checks in a few more items)
Note: Grant Holliday has never published exactly why they are not the same.

Figure: You should get the same number or more for your TFS2010 server. We’re not worried unless it’s slightly less
