The upgrade of rails from 2.3.16 to 5.0.0 is a major undertaking involving multiple significant version jumps with substantial breaking changes. This is a multi-generational leap that requires a complete application overhaul, including changes to dependency management, routing, mass-assignment security, and core framework patterns. The official recommendation is to upgrade incrementally (e.g., 2.3 → 3.0 → 3.1 → 3.2 → 4.0, etc.) to manage the extensive changes. The thin upgrade is a minor patch with no breaking changes.

Highlights for rails upgrade:

• Rails 2.3 → 3.0: Dependency management shifts from config.gem to the Gemfile with Bundler. Routing syntax is completely new, and many internal APIs, including the ORM, were refactored under the new Merb-influenced architecture.
• Rails 3.x → 4.0: attr_accessible and attr_protected are removed in favor of Strong Parameters, a major security-related change requiring updates in every controller that handles data submission. Plugins from vendor/plugins are no longer supported, and many core components like ActiveResource were extracted into separate gems.
• Rails 4.x → 5.0: Requires Ruby 2.2.2+. Models now inherit from ApplicationRecord instead of ActiveRecord::Base. Returning false in a callback no longer halts the callback chain; throw(:abort) must be used instead.

Source: Official Rails Guides, community migration guides.
Recommendation: This upgrade cannot be performed in a single step. A staged migration plan, following the official Rails upgrade guides for each major version, is required. Expect to rewrite significant portions of the application, especially controllers, models, and configuration files.
