Mattel Shop — Toy E-Commerce Store Upgrade to OpenCart 3
Seamless platform upgrade to OpenCart 3.0 with complete catalog and order history migration, strict preservation of legacy SEO rankings, and automated Google Merchant Center XML feeds.
Client and business
Mattel Shop (mattelshop.com.ua) is a premier branded online retailer in Ukraine presenting authentic toys from world-renowned brands including Barbie, Hot Wheels, Fisher-Price, Monster High, and Mega Bloks.
Starting point and brief
The store operated on an outdated OpenCart 1.5/2.x version with severe technical debt: PHP 5.6 dependency, unsupported modules, lack of mobile optimization, and non-compliance with modern Google Merchant Center requirements. The top priority was migrating thousands of products, customer records, and order histories while rigorously protecting historical search positions and URL structures.
OCStudio solution
OCStudio executed a staged modernization and migration protocol: architected a clean OpenCart 3.0 instance running on PHP 8.1 with modern responsive UI and optimized checkout UX, migrated the entire catalog and customer records with 100% data integrity, implemented exact URL parity matching legacy SEO slugs with zero broken links, and developed customized Google Merchant Center feeds.
