next-upgrade

To upgrade Next.js to the latest version, this workflow detects your current version from package.json, fetches official migration guides, executes codemods to apply breaking changes automatically, and updates dependencies. It supports incremental version jumps across App Router and Pages architectures.

Yes, you can migrate Next.js projects using App Router, middleware, and custom server logic. The workflow applies official migration guides and codemod-driven changes to handle breaking changes automatically, minimizing manual edits for complex project architectures.

The best way to handle Next.js major version upgrades is through stepwise compatibility checks. This workflow guides you through incremental version jumps, such as migrating from 13 to 14 to 15, applying codemods and validating builds at each step to ensure stability.

Yes, you may need to perform optional TypeScript type updates after a Next.js migration. The workflow executes codemods, updates dependencies, validates builds through test cycles, and performs these optional type updates to ensure your TypeScript project remains stable.

Your Next.js build may break after manual upgrades due to missed breaking changes. This workflow prevents drift by applying official codemods automatically, synchronizing dependencies, and validating build and test cycles to ensure stability after the upgrade.
