Install cvs2svn with git support:

cd /usr/ports/devel/cvs2svn
make install
make clean
mkdir migrate-old-repos-to-git
cd !$
cp /usr/local/share/examples/cvs2svn/cvs2git-example.options cvs2git.options

Edit the file like this:

 diff -ud cvs2git.options.old cvs2git.options                                                  idefix@server
