Wow - Don't miss this hotfix if you are upgrading TFS 2008 to 2010

Here's what happens if you don't apply the hotfix as part of the upgrade...

"After upgrading to TFS 2010, one or more of the following symptoms may be exhibited:

  • Labels that were created before the upgrade are missing files or folders.
  • Labels could be entirely empty.
  • The Merge wizard in Visual Studio does not display all valid merge targets for a given source path/branch.
  • During merging, merge candidates are shown for changes that were already merged prior to the upgrade."

Brian Harry has a blog post on it and here's the link to the hot fix.
