This is a massive upgrade involving multiple major versions across the entire framework, introducing significant breaking changes. A direct upgrade is not feasible; it must be performed incrementally. Key changes include the introduction of Strong Parameters, a required Ruby version bump to 2.2.2+, and the extraction of core functionality into separate gems.

• rails 3.1.0 → 5.0.0 (high): This upgrade spans four major versions (3.2, 4.0, 4.1, 4.2, 5.0) and contains numerous breaking changes. The upgrade must be done incrementally, for example from 3.1 to 3.2, then to 4.0, and so on. Key breaking changes include the replacement of attr_accessible with Strong Parameters, a required Ruby version of 2.2.2+ for Rails 5.0, and the extraction of features like ActiveRecord observers and page caching into gems. Models now inherit from ApplicationRecord, and migrations must be versioned (e.g., [4.2]).

• jquery-rails 1.0.14 → 4.0.1 (medium): This major version upgrade aligns with modern Rails and jQuery versions. While jquery-rails itself primarily provides assets, the underlying jQuery 4.0 removes support for legacy browsers like IE and deprecates several APIs. The primary risk is if the application relies on deprecated jQuery functionality.

• sass-rails 3.1.3 → 5.0.5 (medium): The upgrade to version 5.0 deprecates the use of .css.scss and .css.sass extensions, requiring file renames. Version 6.0 transitions the gem to be a wrapper around sassc-rails, which uses LibSass instead of Ruby Sass and may have compatibility differences.

Additional upgrades include coffee-rails 3.1.1 → 4.1.1 (low), which is a minor update with no significant breaking changes cited.

Recommendation: Do not merge directly. A staged upgrade is required, moving from Rails 3.1 → 3.2 → 4.0 → 4.1 → 4.2 → 5.0. Address deprecation warnings and gem compatibility at each step.
