Many corporate environments still use Subversion (SVN) for version control. Switching to Git can be a disruptive step that's often postponed.
In this session, an approach will be presented that has been taken for switching a SVN-based development environment to a Git/Gerrit workflow in a less disruptive and flexible way. The approach consists of
migrating a large number of interconnected SVN repositories to a Git mono-repo, and
establishing a birectional hot-sync between Git and SVN, allowing to concurrently use both Git and SVN.
The implemented hot-sync allows to flexibly switch to Git, and the change-based Gerrit workflow was an enabler for it.
The presentation will cover key concepts of the migration; it also provides a summary of the modifications to Gerrit and the hooks plugin for supporting the hot-sync setup.
