I have two production Laravel applications running smoothly on PHP 7.5, and it is time to move them both to PHP 8.2. Each project includes several custom-built modules, so the task goes well beyond a simple composer update. Your mission is to audit the current codebases, refactor anything that breaks under PHP 8.2 (type changes, deprecated functions, strict typing issues, etc.), update third-party packages as needed, and hand the projects back fully tested and ready for deployment. Key points for context • Framework: Laravel (both projects) • Custom features: yes—multiple bespoke modules that must keep working exactly as they do now. Deliverables 1. Two upgraded repositories running on PHP 8.2 with no deprecated warnings or breaking errors. 2. Updated composer.json / composer.lock and any relevant config files. 3. A concise change log explaining what was modified, why, and where. 4. Verification steps or test results proving everything still functions (automated tests, manual test script, or both). Acceptance criteria – Applications boot locally on PHP 8.2 with artisan serve. – All existing routes, jobs, commands, and custom modules behave identically to production. – No failed unit or feature tests; new tests added if code was refactored. – Composer install finishes with zero dependency conflicts or deprecation notices. If you have tackled similar Laravel version jumps before, especially those involving heavy custom logic, I would love to hear how you plan to approach this upgrade and keep downtime to an absolute minimum.
