Code Migration

Modernize legacy systems without slowing development

Run your migration as one coordinated rollout, not 200 manual ones.

Trusted by the world's largest dev teams

Migrations in flight, everywhere at once

Every organization has migrations in flight: framework upgrades, dependency replacements, system rewrites, code-host consolidation, language version bumps. But migrations rarely happen all at once. They happen repo by repo, team by team. Tracking progress is difficult. Ensuring consistency is harder.

The result
  • Slow, fragmented migrations
  • Missed updates and lingering legacy code
  • High coordination overhead
  • Incomplete migrations that quietly unwind

How teams solve it with Sourcegraph

Understand migration scope Identify every instance of deprecated code, libraries, or patterns across all repos before writing a single line.

Oversee progress and risk Track changes, check for consistency, and watch for regressions as the migration rolls out.

Evolve systems at scale Apply coordinated updates as a single rollout, with every change previewed before merge.

Let your agents run the full migration workflow from one platform

Batch Changes

Batch Changes. Apply coordinated PRs across hundreds of repositories.

Deep Search. Discovery and migration spec generation in natural language.

Code Search. Identify deprecated code and patterns across all repos.

Code Navigation. Understand the blast radius of every change before making it.

Code Insights. Track migration progress against the deadline.

Code Monitoring. Alert when deprecated patterns reappear.

Ship the migration on the date you committed to

Ship on schedule. Coordinate all repo changes as a single rollout, not team by team.

Complete coverage. Know every instance is found and updated before you ship.

Track against deadlines. See migration progress across all repos in real time.

Agent-ready. Give migration agents the cross-repo context to make accurate, deterministic changes.
