I run an e-commerce store on an older release of OpenCart and it’s time for both a technical and visual refresh. Here’s what I need done: • Create a full backup and set up a staging environment. • Install the latest stable OpenCart version, then migrate my existing store to it without data loss. • Make sure every current extension, shipping and payment method, and any custom code keeps working exactly as it does now. When conflicts arise, please patch or update the add-ons rather than removing them. • Redesign the homepage with a clean, contemporary look that loads quickly and is fully responsive. I’m open to theme suggestions or custom layout work, as long as the end result feels modern. • After migration and design work, perform functional and cross-browser testing, fix any bugs you find, and deliver the site ready for me to flip live. Acceptance criteria – Latest OpenCart version shows in admin dashboard with no errors or deprecated warnings. – All catalog, checkout, and admin workflows function as they did before the upgrade. – Homepage passes Google Lighthouse core web-vitals in the green for mobile and desktop. – I receive a brief change log and instructions on any new admin settings introduced by the update. If you’ve handled similar upgrades and can work confidently with OpenCart themes, modules, and vQmod/OCmod tweaks, I’d love to hear how long you’ll need and what access you require to get started.
