This major version upgrade from Rails 3.0 to 5.0 spans multiple significant releases and introduces substantial breaking changes, requiring a staged migration (e.g., 3.x → 4.0 → 4.2 → 5.0) and significant code modifications.

Highlights:

• Replace Mass-Assignment Protection: attr_accessible is removed. Migrate to Strong Parameters in controllers before upgrading.
• Update Ruby Version: Rails 5.0 requires Ruby 2.2.2 or newer.
• Adopt New Model/Job Superclasses: Models must inherit from ApplicationRecord instead of ActiveRecord::Base, and jobs from ApplicationJob.

Source: Official Rails Guides
Recommendation: A staged upgrade is required. First, migrate to Rails 4.2, addressing Strong Parameters and gem compatibility. Then, proceed with the upgrade to Rails 5.0, updating models, jobs, and callbacks.
