Enterprise Shopify Plus Migration Services: Move from Magento or BigCommerce with Confidence

For enterprise brands currently tethered to legacy platforms like Magento 1, Magento 2, or BigCommerce, the move to Shopify Plus is more than a platform change—it is a strategic pivot toward agility and lower total cost of ownership. However, the complexity of migrating 50,000+ products, decades of customer order history, and intricate ERP integrations requires a partner with a proven methodology. Mejix is a Shopify Plus Partner at the Plus Tier, specializing in high-stakes migrations that demand technical precision.

Our migration process is engineered to eliminate the common pitfalls of replatforming. We focus heavily on SEO preservation, ensuring that every URL structure and redirect is meticulously mapped so your organic rankings remain stable. From our New York office, our team manages the entire lifecycle of the migration, from initial data auditing to the deployment of custom checkout extensions and Shopify Flow automations. We don't just move your data; we modernize your entire commerce architecture.

Mejix brings deep experience in transitioning complex Magento ecosystems to the streamlined, scalable environment of Shopify Plus. One of our hallmark projects involved migrating a large furniture retailer with over 50,000 products from Magento 1 to Shopify Plus. This migration required not only the movement of massive datasets but also the integration of a Sales Layer PIM and custom payment gateways. The result was a restoration of site performance, real-time stock accuracy, and a significantly higher conversion rate.

When you hire Mejix as your Shopify Plus migration agency, you are hiring a team that understands the enterprise 'why.' We recognize that your ERP, whether it’s NetSuite, SAP, or a custom build, is the heartbeat of your business. Our engineers specialize in building robust middleware and utilizing Shopify’s APIs to ensure that your back-office operations remain synchronized throughout the migration and beyond. We prioritize zero-downtime launches, allowing your business to continue generating revenue while we handle the technical heavy lifting.
