Instead of doing an all-or-nothing SVN to Git conversion, we gradually transition individual libraries out of SVN and into Git submodules using svn:externals i.e. you wipe library X from SVN, replacing it with an svn:externals which loads a Github provided SVN translation from Git (https://help.github.com/articles/support-for-subversion-clients) for that particular library submodule. This lets maintainers test their particular library to make sure it really works as a git submodule, and "detach" its write access from SVN. Slowly, over time, we therefore transition from all-SVN write access, through some-SVN some-Git write access, to all-Git write access, with the SVN repo eventually becoming a "shell" of links to git modules and whose svn revision no longer increments.
I think that is exactly the approach that was taken by KDE.
