This is a multi-generational upgrade from Rails 2.3 to 5.0, which is not a direct path and requires a complete application overhaul. A sequential upgrade (e.g., 2.3 → 3.2 → 4.2 → 5.0) is mandatory. Key breaking changes include the introduction of Strong Parameters for security, the replacement of before_filter with before_action, and fundamental architectural shifts like the Asset Pipeline and new model inheritance from ApplicationRecord.

Highlights:

• Mandatory Security Update (Rails 4+): Mass assignment protection via attr_accessible is removed. You must migrate to Strong Parameters in your controllers, which requires explicitly permitting attributes (e.g., params.require(:model).permit(:attr)).
• Controller Callbacks (Rails 5): The before_filter callback is deprecated and removed. All instances must be replaced with before_action.

Source: Official Rails Guides
Recommendation: Do not merge directly. A staged migration is required. Follow the official Rails upgrade guides for each major version sequentially, starting with the upgrade from Rails 2.3 to 3.0.
