I understand this is a strict compatibility upgrade to PHP 8.4 with zero impact on your current functionality or layout—and that’s exactly how I’d approach it. I’ll first audit your existing codebase for deprecated functions (e.g., removed PHP 8.x features, legacy MySQL calls, error handling), then test everything in a staging environment before touching live. Special focus will be on PayPal integration, admin panel, email triggers, and JS components like scrollers, ensuring they behave identically post-upgrade. I’ll also validate all pages against W3C standards and test across Chrome, Safari, and mobile to guarantee no visual or functional regressions. The live site will remain uninterrupted—I’ll deploy changes safely after full verification. I’ve handled similar PHP version migrations where stability and backward compatibility were critical. Looking forward for your positive response in the chatbox. Best Regards, Arbaz Ali
