My website, user panel, and admin panel currently run on Core PHP 7.4.33. I want the entire codebase lifted into Laravel 12 while preserving every existing feature, setting, and piece of data exactly as users know them today. Here is the scope I need you to cover: • Full off-server backup of all site files and the database before any work begins • A staging environment where the migration happens and can be tested end-to-end • Upgrade of the underlying CMS / framework logic to Laravel 12, plus refactoring of custom PHP where required • Updates to every theme, plugin, and library so they officially support Laravel 12 • Parity testing of the public site, user panel, and admin panel to confirm no functionality breaks • Security hardening during the move—input sanitisation, updated dependencies, and best-practice server configs, security headers • Audit of the current code for any third-party API calls or services (I’m not 100 % sure what’s in there) and seamless reconnection after the upgrade • Smooth cut-over from staging to production once everything passes review Acceptance criteria: 1. All pages load without errors under Laravel 12. 2. User flows, admin tools, and existing settings behave exactly as they do today. 3. No data loss; database schema migrated cleanly. 4. Independent security scan shows no critical or high-severity issues. 5. Detailed hand-off documentation: steps taken, updated libraries, and roll-back instructions. If you have proven experience modernising Core PHP applications and hardening them along the way, let’s talk about timelines and your approach.
