We are currently getting a "503 Service Unavailable" error on the login screen because the legacy code cannot process the new PHP version.We have a very tight budget for this fix, but we have made the job as clean and organized as possible for you. We have a complete, uncorrupted backup of both our CRM file directory (.zip) and our complete database (.sql) safely downloaded from CodeGuard from just before the crash.Your tasks will be:Set up a temporary local development environment on your own computer running older PHP 7.4.Restore our Vtiger 7.3 backup files and database into your environment to make sure it loads smoothly.Manually run the sequential Vtiger migration patches in the exact required order: Vtiger 7.3 → 7.4 → 7.5 (adds initial PHP 8 support) → Vtiger 8.x (full PHP 8.2/8.3 compatibility).Ensure the database tables and schemas update correctly without losing any customer data history.Upload the newly modernized, PHP 8-compatible Vtiger code back to our
