Rails Upgrade Latest

Use this skill to execute Rails upgrades with predictable checkpoints and minimal downtime risk.

Workflow

1. Confirm baseline and target:

• Detect current Rails/Ruby versions from Gemfile.lock, ruby -v, and bin/rails -v.
• Determine the latest stable Rails target and required Ruby version.
• If the jump spans multiple versions, upgrade one minor/major step at a time.

2. Read the upgrade references:

• Open references/upgrade-workflow.md and follow the sequence.
• For each version jump, read that version's release notes before changing code.

3. Prepare safety rails:

• Ensure branch isolation and clean git status.
• Ensure strong test coverage for core user flows before version changes.
• Remove or update unsupported/deprecated gems first.
