This is a multi-generational upgrade across three major versions (2.x → 3.x → 4.x → 5.x) and represents a complete framework overhaul. A direct upgrade is not feasible; an incremental approach is required. Key architectural changes include the introduction of Bundler for gem management, the asset pipeline, Strong Parameters for security, and a complete rewrite of core components.

Highlights:

• Rails 3: Introduced Bundler, a new routing DSL, and made all core components decoupled.
• Rails 4: Replaced attr_accessible with Strong Parameters and removed vendor/plugins.
• Rails 5: Requires Ruby 2.2.2+, introduces Action Cable for WebSockets, and makes models inherit from ApplicationRecord.

Source: Official Rails Guides
Recommendation: Do not attempt a direct upgrade. Follow official guides to upgrade sequentially through major versions (e.g., 2.3 → 3.2 → 4.2 → 5.0) to manage the extensive breaking changes.
