What is the best way to migrate from the classic autoloader to Zeitwerk for a Rails upgrade?▼

Migrating to the Zeitwerk autoloader is automated during the Rails upgrade process to ensure compatibility with newer framework versions, handling the transition from the classic autoloader smoothly without manual intervention.

How do I adopt new framework defaults incrementally during a Rails modernization?▼

You adopt new framework defaults incrementally by following the guided upgrade path, which updates assets, jobs, cache, cable, and secrets step by step to maintain application consistency throughout the modernization.

Can I update my legacy Rails application to the newest framework version without downtime?▼

Yes, the Rails upgrade process is designed to minimize risk and downtime by performing version increment checks and guiding the application through a step-by-step incremental framework version migration.

Why does my Rails upgrade require updating framework defaults for assets and cache?▼

Updating framework defaults for assets, jobs, cache, cable, and secrets is required during a Rails upgrade to ensure your application maintains consistency and compatibility with the latest framework versions.

When do I need to run an incremental Rails upgrade instead of jumping to the latest version?▼

You need an incremental Rails upgrade when moving from a legacy version, allowing you to perform version increment checks and adopt new framework defaults gradually to avoid breaking application functionality.
