About Ruby on Rails 4.2
Ruby on Rails 4.2 reached end of life over 8 years ago on April 27, 2017. It no longer receives security patches, bug fixes, or any form of official support. Running this version in production exposes your systems to unpatched vulnerabilities and growing incompatibility with modern libraries and tooling.
The recommended upgrade target is Ruby on Rails 8.1. You are 3 major versions behind, so review the changelog for each version in between to catch any breaking changes. A staged upgrade through each major version is often safer than jumping directly.
