The problem
Big migrations stall. Teams can't afford the multi-quarter project to upgrade React, swap an SDK, or move off a deprecated framework.
What the agent does
- Plans the migration in incremental, mergeable PRs
- Runs the codemod, fixes type errors, and updates tests
- Posts a status PR with deltas and a recommended human review focus
Business value
Compresses migrations from quarters to weeks and avoids the staffing tradeoff vs. feature work.
