Urgent: Upgrade Legacy Vtiger CRM (7.3 to 8.x) due to Host PHP 8 Update

Hello,Our company website hosting (Bluehost) recently forced an automatic update to PHP 8.3. This has completely broken our internal business CRM portal, which runs on an older version of Vtiger CRM (Version 7.3). 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 live Bluehost File Manager.What we will provide:A Google Drive link containing the clean CodeGuard file backup and database backup.Temporary cPanel login credentials to our hosting account.Please apply if you have experience with Vtiger or database migrations and are willing to help a small business get back on its feet within our budget. Thank you!
