      Help me migrate from the hex.pm package "#{from}" to "#{to}".

      Use get_package_info and get_package_docs on both packages to understand their APIs.
      Use compare_packages to see how they differ in stats and health.

      Provide:
      - Why migrate: Key differences and advantages of the target package
      - API mapping: How concepts/functions map between the two
      - Breaking changes: What will need to change in existing code
      - Migration steps: Ordered list of changes to make
      - Testing strategy: How to verify the migration works
