SubGit

SubGit is a migration tool that converts Subversion repositories to Git while keeping both systems operational in parallel. It is installed on the target Git server—Git, GitLab, or Bitbucket—and automatically detects the remote SVN configuration, downloads SVN revisions, and translates them into Git commits. After the initial conversion, SubGit maintains a bidirectional mirror: pushes to Git are reflected back to SVN, and new SVN revisions are pulled into Git, allowing users of either system to see each other’s changes as if working in a single repository.

The software is aimed at development teams that need to transition from SVN to Git without interrupting ongoing work. By providing continuous synchronization, it lets developers continue using their preferred VCS while the migration proceeds, reducing the risk of conflicts and preserving repository history. SubGit supports macOS and other platforms, and it is positioned as a stable, production‑ready solution with a history of thousands of successful migrations.
