So you want to take those old CVS repositories and migrate them to Git?
You can use cvs2git to migrate your
CVS repository with history to Git. It requires direct filesystem access the CVS
repository that you wish to convert.
Fist download cvs2git, compile, and install.
Now you are ready to convert a repository's history into git fast-forward format.
cvs2git only migrates history so you need to add all the files to Git yourself.
Now import the history and push it all to the origin.
