For all the SVN users that likes to migrate to TFS 2010 with all the history of SVN here is the right tool for you:

http://svn2tfs.codeplex.com/

This tool will help to Migrates a SubVersion 6.x (SVN) repository to Team Foundation Server (TFS) 2010 replaying every action occurred in SubVersion.

Note: I haven’t tested the tool yet, I will let you know when I will test it.

Have Fun!!!
