Git and Other Systems
The world isn’t perfect. Usually, you can’t immediately switch every project you come in contact with to Git. Sometimes you’re stuck on a project using another VCS, and many times that system is Subversion. You’ll spend the first part of this chapter learning about
git svn, the bidirectional Subversion gateway tool in Git.
At some point, you may want to convert your existing project to Git. The second part of this chapter covers how to migrate your project into Git: first from Subversion, then from Perforce, and finally via a custom import script for a nonstandard importing case.
