Portmux is a Magento to Shopify migration service that moves your Magento 2 catalog, customer segments, multi-store views, and order history into Shopify or Shopify Plus, with the URL redirect strategy that keeps your organic search traffic intact.
Magento 2 is a powerful platform but expensive to maintain (PHP/MySQL hosting, security patches, extension conflicts). Most teams move to Shopify or Shopify Plus to drop the ops overhead. The catalog model is more complex than WooCommerce, Magento has Configurable Products, Bundle Products, Grouped Products, multi-store views, and customer segments tied to advanced rule logic, all of which need explicit translation to Shopify.
Simple, Configurable, Grouped, Bundle, Virtual, and Downloadable products migrated to Shopify Products with type-appropriate variant or product structure.
Magento Configurable Products with Super Attributes (Size, Color, etc.) mapped to Shopify products with up to 3 option types and 100 variants.
Magento Bundle Products migrated as Shopify products with the bundle items represented via a bundle app (Shopify Bundles, Bundles.app) or as line item properties.
Magento custom attributes (text, dropdown, multi-select, swatch) migrated to Shopify Metafields with appropriate type definitions.
Magento Categories with multi-level hierarchy mapped to Shopify Collections (Custom or Smart) with the hierarchy flattened where needed.
Customer accounts migrated with addresses, customer groups, and store credit balances; Magento Customer Segments translated to Shopify Customer Segments with rule logic.
Full order history migrated with line items, applied catalog/cart price rules, taxes, shipping, fulfillments, refunds, and Magento order status preserved as fulfillment + financial status.
Active Magento Catalog Price Rules and Cart Price Rules re-implemented as Shopify Discounts (Automatic, Code, Buy-X-Get-Y) with the same conditions and actions.
Magento CMS Pages migrated to Shopify Pages; CMS Blocks become Shopify theme sections or app-managed content blocks.
Magento URL Rewrites migrated as Shopify URL Redirects; every live product/category/page URL mapped to its new Shopify path as a 301 redirect.
Magento Store Views (different languages, currencies, or domains) mapped to Shopify Markets (Plus) or to separate Shopify stores depending on requirements.
Magento Tax Rules and Tax Classes re-derived as Shopify tax overrides per region, or wired to a tax service (Avalara, TaxJar) at cutover.
We connect to Magento 2 via REST API and direct MySQL read replica access (Magento's API doesn't expose every entity efficiently). The schema map covers all product types, attribute sets, category trees, customer groups, and price rules. Within 72 hours you see a complete catalog inventory and a multi-store-view-to-Shopify-Markets mapping proposal.
Mapping decisions: Configurable Product to Shopify variants (handling cases over 100 variants), Bundle Products to Shopify bundle apps, multi-store views to Shopify Markets vs separate stores, customer segments to Shopify Customer Segments. We also build the URL redirect map at this stage so SEO planning happens before the catalog moves.
Shopify or Shopify Plus staging store loaded with full catalog, customers, and order history. Your team QAs the storefront, checkout, multi-currency (if Shopify Markets), and tax. On cutover day, DNS flips to Shopify, the URL redirect map (often 50K+ entries for large Magento catalogs) is pushed via Shopify Redirects API, and search engines get the new sitemap.
Every migration has its own gotchas. Here's what we plan for on this specific path.
Magento Configurable Products can have unlimited variants. Shopify caps at 100 variants and 3 option types. Products that exceed need re-modeling, splitting into multiple Shopify products by one option dimension (e.g. one product per Material), or using an app like Infinite Options to expose additional choices outside the variant SKU.
Magento Bundle Products (where customers pick options to assemble a custom bundle) don't have a native Shopify equivalent. We use Shopify Bundles (the native app), Bold Bundles, or implement bundles via line item properties depending on the product UX you want to preserve.
Magento Multi-Store Views often share a catalog but diverge on language, currency, or domain. Shopify Markets handles multi-currency and multi-language well; Multi-Store views with different domains often map to separate Shopify stores instead. We pick the right architecture per store view based on operational needs.
The Magento extension marketplace is broader than Shopify's app store, particularly for B2B (company accounts, quote management, requisition lists). We catalog every active extension, find the closest Shopify app equivalent, and flag gaps for custom app development if needed.
Single-system migrations like Magento to Shopify run as Track A engagements: one source, one destination, up to 1M records, 4–6 weeks. Final price depends on object volume, custom field count, and integrations, scoped on a 20-minute call before any commitment. See full pricing →
