next-upgrade

To upgrade Next.js safely, follow a guided workflow that applies official codemods and validates dependencies incrementally. This approach enforces reading package.json, updating next/react packages stepwise, and testing builds to reduce risk and downtime.

Codemods automate the application of breaking changes during a Next.js migration. They safely rewrite code according to official migration guides, handling incremental version steps to ensure compatibility when moving across major releases.

Yes, you can migrate from Next.js 13 to 15 incrementally by stepping through intermediate versions like 14. The workflow validates dependencies and applies codemods at each stage, verifying builds and runtime behavior before moving to the next major release.

The best way to handle dependency updates during a Next.js upgrade is to validate them alongside official migration resources. The workflow reads package.json, updates next and react packages together, and tests builds to ensure compatibility.

Next.js upgrades often break apps when stepping across major versions due to unhandled breaking changes and incompatible dependencies. Applying automated codemods and following official migration guides helps safely apply breaking changes and validate runtime behavior.
