This is a massive upgrade across four major versions (3.0 → 3.2 → 4.0 → 5.0) and introduces fundamental, application-wide breaking changes. The migration requires a multi-step process and significant code modifications. Key changes include the mandatory adoption of Strong Parameters, a complete overhaul of the asset pipeline, and a required Ruby version update.

Highlights:

• Adopt Strong Parameters: The attr_accessible and attr_protected methods in models are removed and must be replaced with Strong Parameter sanitization in controllers.
• Migrate Asset Pipeline: Assets must be moved from public/ to the app/assets directory and managed via Sprockets manifest files (e.g., application.js/application.css).

Source: Ruby on Rails Guides, Official Release Notes
Recommendation: Do not merge directly. Follow the official Rails upgrade guides incrementally, from version 3.0 → 3.1 → 3.2 → 4.0 → 4.1 → 4.2 → 5.0, addressing deprecations at each step.
