We refreshed the documentation on http://tfsintegration.codeplex.com/ this morning, to correct errors, add more details around limitations that need to be known and adding new content to the documentation, such as the TFS_Integration_Platform-Subversion_Migration document which was created by external Rangers.
The limitations link on the front page of the code plex site doesn't work. It's pointing to tfsintegration.codeplex.com/.../wikipage which does not exist.
Thank you for reporting this gremlin. We fixed the homepage and the link now refers to the Migration Guidance document which outlines the limitations.
