SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Upgrading a Rails application from 7.x to 8.0 introduces breaking changes from new default stack components (Solid Queue, Propshaft, built-in authentication) and accumulated deprecations across minor versions. Teams often rush the upgrade, adopting all new defaults at once and breaking existing functionality, or skip minor version hops and pile up unfixable deprecation warnings.

Core Features & Use Cases

  • Staged dual-boot upgrade workflow: Guides teams through the 7.0 → 7.1 → 7.2 → 8.0 hop sequence using next_rails to avoid breaking the main branch.
  • Optional default adoption guidance: Provides clear decision frameworks for adopting new Rails 8 defaults (Solid Queue, Solid Cache, Propshaft, built-in auth) only after the version upgrade is stable, avoiding unnecessary rework.
  • Use Case: A team running Rails 7.0 with Sidekiq, Devise, and a custom Sprockets asset pipeline can use this skill to upgrade to Rails 8.0 in 3 separate PRs, keeping their existing tooling intact until they are ready to adopt new defaults.

Quick Start

Use the rails-upgrade-7-to-8 skill to plan and execute a staged upgrade of your Rails 7.x application to Rails 8.0, including dual-boot configuration and deprecation remediation steps.

FAQPage Schema
How do I safely upgrade my Rails 7 application to Rails 8 without breaking existing functionality?▼

To safely upgrade Rails 7 to Rails 8, use a staged dual-boot workflow that sequences minor version hops from 7.0 to 7.1, 7.2, and then 8.0 using the next_rails gem. This approach isolates deprecation remediation and prevents breaking your main branch.

What is the best way to handle deprecated features when upgrading to Rails 8.0?▼

Handling deprecated features during a Rails 8.0 upgrade requires remediating deprecation warnings at each minor version hop. Skipping intermediate versions like 7.1 or 7.2 can pile up unfixable warnings, so a staged progression is recommended.

Do I need to adopt Propshaft and Solid Queue immediately when upgrading to Rails 8?▼

No, adopting Propshaft and Solid Queue is optional when upgrading to Rails 8. You should use decision frameworks to adopt new default stack components only after the core version upgrade is stable, avoiding unnecessary rework.

Why does upgrading Rails 7.x to 8.0 in a single step break my application?▼

Upgrading Rails 7.x to 8.0 in a single step breaks applications because it introduces breaking changes from new default stack components and accumulated deprecations across minor versions simultaneously, requiring a staged dual-boot workflow to manage safely.

Can I use dual-boot configuration to test my Rails 8 upgrade without affecting production?▼

Yes, you can use dual-boot configuration with next_rails to test your Rails 8 upgrade alongside your current version. This staged rollout planning allows version compatibility validation and deprecation remediation without breaking the main branch.
