Migrate from SVN to Git
Move your Subversion repository to Git with full commit history, author mapping, and branch preservation — unlocking modern development workflows.
Migration: SVN to Git
From Apache Subversion (SVN) to Git (GitHub/GitLab)
Why Migrate
- Distributed Workflows: Git's distributed model lets every developer work with a full local copy, enabling offline work, faster operations, and flexible branching strategies.
- Modern Tooling: Git integrates with GitHub, GitLab, CI/CD pipelines, code review tools, and the entire modern DevOps ecosystem that SVN cannot access.
- Superior Branching: Git branches are lightweight and fast. Feature branches, release branches, and pull request workflows become practical instead of painful.
Migration Roadmap
- SVN Analysis (3–5 days): Analyze SVN repository structure (trunk/branches/tags), author list, commit history size, and any svn:externals dependencies.
- Repository structure analysis
- Author mapping file
- Migration complexity assessment
- History Conversion (1–2 weeks): Use git-svn or svn2git to convert the SVN repository to Git, preserving full commit history, branches, tags, and author attribution.
- Git repository with full history
- Branch and tag conversion
- Large file handling with Git LFS
- Workflow Setup & Cutover (1 week): Configure Git hosting (GitHub/GitLab), set up branch protection rules, CI/CD pipelines, and onboard the team on Git workflows.
- Hosted Git repository
- Branch protection and CI/CD
- Team training documentation
- SVN read-only lockdown
Risks & Mitigation
- SVN history is very large and conversion takes too long: We use incremental migration with git-svn fetch, processing history in batches. For extremely large repos, we offer a clean-cut migration with archived SVN history.
- svn:externals dependencies break in Git: We replace svn:externals with Git submodules or a monorepo strategy, ensuring all cross-repository dependencies continue to resolve correctly.
Estimated Scope
Hours: 40–100 | Cost: $80–$200 | Timeline: 2–4 weeks
Frequently Asked Questions
- Will we lose any commit history?
- No. We use git-svn to convert every SVN commit to a Git commit with the original author, date, and message preserved. The full history is maintained.
- How do you handle SVN branches and tags?
- SVN branches and tags (which are just directory copies) are converted to proper Git branches and lightweight tags with correct ancestry.
- Can you migrate multiple SVN repositories?
- Yes. We handle bulk migrations, either combining multiple SVN repos into a Git monorepo or creating separate Git repositories for each.
