Code Migration Skill

Safely migrate codebases between frameworks, libraries, and architectural patterns with minimal risk.

When to use this skill

• Upgrading Next.js versions (currently on 16.2.9 with --dangerouslyUseUnsupportedNextVersion)
• Upgrading React versions (currently on 18.x with React 19 in Sanity studio)
• Updating Sanity packages (sanity, next-sanity, @sanity/client)
• Migrating between UI libraries or animation frameworks
• Updating @opennextjs/cloudflare or wrangler
