WooCommerce to Shopify Migration for Fashion With Product Catalog Migration, Extension-to-App Replacement, SEO Redirect Implementation, Custom Theme Development, and Revenue-Preserving Cutover

Our WooCommerce to Shopify migration for fashion covers audit, data extraction, Shopify configuration, theme development, data import, testing, and cutover.

Audit documents the WooCommerce store completely. We extract and catalog: every product with its type (simple, variable, grouped, external — each requiring different migration handling), all product attributes and variations (WooCommerce variable products map to Shopify variant products, but attribute structures differ and require transformation), all product images with their assignments (featured image, gallery images, variation-specific images), all product categories and tags (mapped to Shopify collections and tags), every active plugin with its function (identifying the Shopify app equivalent or custom development requirement), all pages and blog posts (migrated to Shopify pages and blog), customer accounts with their order history, coupon and discount configurations, shipping zones and methods, tax configurations, and the complete URL structure (for redirect mapping). The audit identifies potential migration issues — products with more than 100 variants (Shopify's limit), products with more than 3 variation attributes (Shopify supports 3 options), and plugin functionality without direct Shopify equivalents.

Data extraction pulls all data from WooCommerce for transformation. We use WooCommerce's REST API for structured data extraction — products, customers, orders, and coupons are exported through API endpoints that provide clean, structured data. For product images and media files, we extract directly from the WordPress uploads directory to preserve full-resolution originals. Custom field data (from ACF, custom metadata, or specialized plugins) is extracted through database queries to capture information not available through the standard API. The extraction produces structured data files — typically JSON — that serve as the source for transformation.

Shopify configuration sets up the Shopify store before data import. We configure: payment processing (Shopify Payments for primary processing, with additional gateways as required — PayPal, Apple Pay, Google Pay), shipping (zones matching the WooCommerce configuration with carrier-calculated rates, flat rates, or free shipping thresholds), taxes (automatic tax calculation replacing WooCommerce's tax configuration — with manual overrides for fashion-specific exemptions), customer notifications (transactional emails styled to match the brand — order confirmation, shipping confirmation, refund notification), and Shopify apps (Klaviyo for email marketing, Loox or Judge.me for reviews, and any additional apps replacing WooCommerce plugins).

Theme development builds the custom Shopify storefront. We design and develop using Online Store 2.0 architecture — section-based templates that give the merchandising team flexibility without developer dependency. Key template designs include: homepage (hero section, featured collection, editorial content, brand story — customizable through the Shopify theme editor), collection pages (grid or list view, visual filters for size, color, price, and brand, sort options, and quick-add-to-cart functionality), product pages (large product imagery with zoom, variant selection with visual swatches for color, clear size guide integration, related products, and recently viewed products), cart and checkout (Shopify's native checkout with custom branding, upsell recommendations, and dynamic shipping calculations), and editorial pages (blog, lookbooks, about — leveraging Shopify sections for flexible content layouts).

Data import loads the transformed data into Shopify. Products are imported with all variants, images, SEO data, and metafield values. We validate the import by comparing product counts, variant counts, image counts, and spot-checking product details across the catalog. Customer accounts are created with tagged customer groups and associated order history. Collections are configured with automated rules (tag-based, product type-based, or vendor-based membership) that replicate the WooCommerce category structure while adding Shopify-native merchandising capabilities.

Testing validates the complete Shopify store before cutover. We test: product browsing (filtering, sorting, search, and navigation across all collection types), purchase flow (add to cart, cart update, checkout with each payment method, order confirmation), customer accounts (login, order history, address management, password reset), mobile experience (product browsing, checkout, and account management on iOS and Android devices), email flows (transactional emails and marketing automation sequences), integrations (fulfillment, analytics, and marketing tool connections), and performance (page load times across all page types, compared to WooCommerce baselines).

Cutover transitions the live domain to Shopify. DNS records are updated to point to Shopify during a scheduled low-traffic window. URL redirects are activated — every WooCommerce URL redirects to its Shopify equivalent using 301 permanent redirects. We monitor search console, analytics, and sales data for the first 48 hours. The WooCommerce site is preserved on a staging domain for 2 weeks as a reference and rollback option.

WooCommerce to Shopify migration for fashion ranges from $15,000 to $60,000 depending on catalog size and theme complexity. Small store migration (under 200 products, premium Shopify theme customization, basic data migration) costs $15,000 to $25,000 across 4 to 6 weeks. Medium store migration (200 to 1,000 products, custom Shopify theme, comprehensive data migration with customer and order history, SEO redirect implementation) costs $25,000 to $40,000 across 6 to 10 weeks. Large store migration (1,000-plus products, complex product data, multiple customer groups, extensive custom functionality replacement) costs $40,000 to $60,000 across 8 to 12 weeks. Post-migration support and optimization runs $1,500 to $3,500 per month for the first 3 months.
