My store is running on an older build of CS-Cart and I’m ready to move to the latest stable release. The job is squarely about upgrade and ongoing maintenance, not feature re-design. Because the installation contains bespoke code tweaks, the upgrade has to be done in a way that keeps every customization fully operational. Here’s how I see it flowing: • Audit the current instance, noting every core file change, override and add-on that could be affected. • Spin up a staging copy, perform the software version upgrade there first, and resolve any conflicts that surface. • Migrate the live database and skin once everything checks out, switching over with minimal downtime. • Provide a concise hand-over document summarising what was touched, how to roll back, and recommended routine maintenance tasks for the next six months. Please be comfortable working directly with CS-Cart’s upgrade center, PHP 8.x, MySQL and Git. A short call at the start will let me give you server access and walk through the custom code so nothing gets overlooked.
