SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes the guesswork from moving a Next.js app to a newer major or minor version by guiding the upgrade with official migration steps and codemods.

Core Features & Use Cases

  • Version Detection: Identifies the current Next.js, React, and related dependency versions before planning the upgrade.
  • Official Migration Guidance: Uses the latest Next.js upgrade and codemod documentation to choose the correct path.
  • Incremental Major Upgrades: Handles multi-version jumps by moving through supported upgrade stages in order.
  • Build and Compatibility Checks: Calls out dependency updates, breaking changes, and validation steps needed after the upgrade.
  • Use Case: A team maintaining an older production site can upgrade to a newer Next.js release while minimizing regressions and avoiding undocumented changes.

Quick Start

Ask the assistant to upgrade the current project to the target Next.js version using the official migration guide and codemods.
