kirby-upgrade-and-maintenance

Quick start

• Follow the workflow below for safe, incremental upgrades.

KB entry points

• kirby://kb/panel/compat-k5-k6-migration
• kirby://kb/panel/tooling-kirbyup
• kirby://kb/glossary/kirbyup
• kirby://kb/glossary/plugin

Required inputs

• Current and target Kirby versions.
• Environment constraints and downtime tolerance.
• Plugin compatibility risks and rollback expectations.

Default upgrade checklist

• Read the target version guide and note breaking changes.
• Update composer.json constraints, then review the lockfile diff.
• Run project scripts and render representative pages.
• Verify runtime commands and CLI version match.

Rollback note

• Keep a copy of the previous composer.lock and vendor/ state.

Rollback checklist

• Restore the previous composer.lock.
• Reinstall dependencies and re-run smoke tests.
• Re-render representative pages to confirm behavior.

Staged upgrade pattern

• Upgrade a single environment/site first, then roll out to others.
• Validate plugins and custom code before multi-site rollout.

Common pitfalls

• Skipping plugin compatibility checks.
• Upgrading multiple major versions in one jump.

Workflow

1. Call kirby:kirby_init or gather baseline data with kirby:kirby_info and kirby:kirby_composer_audit.
2. Inventory plugins for compatibility risks: kirby:kirby_plugins_index.
3. Use kirby:kirby_online to find official upgrade guides and breaking changes for the target version (prefer kirby:kirby_search first).
4. Build a project-specific checklist of required code/config changes.
5. Ask for confirmation before dependency updates that change the lockfile.
6. Verify:
   • run project scripts discovered in the composer audit
   • call kirby:kirby_cli_version to confirm the installed version
   • ensure runtime commands are in sync: kirby:kirby_runtime_status and kirby:kirby_runtime_install if needed
   • render representative pages with kirby:kirby_render_page(noCache=true)
7. Summarize changes, remaining risks, and a short manual QA checklist.
