Do you run Dog Food Stats (after)?
  v4.0 Posted at 11/06/2012 4:51 PM by Damian Brady

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.

  1. On TFS2010, run the DogFoodStats queries and save the results
    (http://blogs.msdn.com/granth/archive/2009/10/23/tfs2010-sql-queries-for-tfs-statistics.aspx) 
  2. Compare the numbers are the same
    1. 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.
TFS2008:

Figure: Have a look at the dogfoodstats you ran before
TFS2010:
=============================================
Areas and Iterations
--------------------
1096

Compressed File Sizes

Uncompressed File Sizes

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