Migration Skill

Migrate existing applications from other platforms to DigitalOcean App Platform.

Quick Start

"Migrate my app from Heroku to App Platform: https://github.com/myorg/myapp"

Supported Platforms

Platform	Support
Heroku	✅ Full
Docker Compose	✅ Full
Render	✅ Full
Railway	✅ Full
Fly.io	✅ Full
AWS ECS	⚠️ Partial
AWS App Runner	⚠️ Partial

What It Does

1. Analyzes your existing app configuration
2. Maps services, databases, and dependencies to App Platform equivalents
3. Identifies what can't be automatically migrated (asks for your input)
4. Refactors code to remove platform-specific dependencies
5. Generates App Platform spec and migration checklist

Philosophy

This skill is an honest partner:

• Maps what it can confidently
• Clearly reports what it cannot map
• Asks for decisions when multiple options exist
• Never guesses or skips items silently

Output

• .do/app.yaml — App Platform specification
• .do/deploy.template.yaml — Deploy button template
• MIGRATION.md — Checklist with mapping status
• Code changes in migration branch(es)

Next Steps

After migration, use:

• deployment skill → Set up CI/CD with GitHub Actions
• postgres skill → Complex database setup
• devcontainers skill → Local development environment
