Upgrade Next.js

Upgrade the current project to the latest Next.js version following official migration guides.

Instructions

1. Detect current version: Read package.json to identify the current Next.js version and related dependencies (React, React DOM, etc.)

2. Fetch the latest upgrade guide: Use WebFetch to get the official upgrade documentation:

   • Codemods: https://nextjs.org/docs/app/guides/upgrading/codemods
   • Version-specific guides (adjust version as needed):
     • https://nextjs.org/docs/app/guides/upgrading/version-16
     • https://nextjs.org/docs/app/guides/upgrading/version-15
     • https://nextjs.org/docs/app/guides/upgrading/version-14

3. Determine upgrade path: Based on current version, identify which migration steps apply. For major version jumps, upgrade incrementally (e.g., 13 → 14 → 15).
