eCommerce Data & Platform Migration, With Nothing Left Behind

When the platform limits the business: features you cannot add, speed you cannot fix, fees that grow with revenue, integrations that fight you, or a theme system your team cannot maintain. The usual trigger is growth; the usual mistake is waiting until the limits cost sales. The free audit gives you the task list for your pair so you can judge the effort before committing.

From BigCommerce, Shopify and Shopify Plus, Magento and Adobe Commerce, WooCommerce and WordPress, or Volusion, to BigCommerce, Shopify, Magento, or WooCommerce: sixteen paths, each with its own page in the matrix above. We also migrate from Wix, Squarespace, PrestaShop, OpenCart, 3dcart, and custom builds, and to headless storefronts on BigCommerce or Shopify.

Products with images, attributes, options, SKUs, pricing, and inventory; categories; customer accounts and addresses; order history with line items and statuses; customer groups and price lists; reviews; blog posts and pages; SEO metadata; and the third-party workflows connected to the store. Passwords cannot move between platforms, so customers set a new one on first login; saved cards and subscription tokens move only with the payment processor's cooperation, which we arrange.

Not when the migration is run as an SEO project. The 2026 studies put the loss for poorly executed migrations at 20 to 40 percent of organic traffic with six to twelve months to recover; the cause is almost always missing or lazy redirects, changed content, and lost internal links. With one-to-one redirects, metadata and schema parity, and thirty days of monitoring, stores typically see a small dip for two to four weeks and full recovery.

A catalog-and-redirects migration with the same design runs four to eight weeks; a refresh or redesign brings most projects to ten to sixteen weeks; large catalogs, ERP connectors, subscriptions, or multiple storefronts extend it to three to six months. We phase launches when a date is fixed: data, SEO parity, and checkout first, the rest second.

Industry ranges in 2026 run roughly $10,000 to $50,000 for a straightforward store move and $50,000 to $250,000 for mid-market migrations with custom data and integrations; the platform license is only a fraction of the total, with implementation, integrations, and data migration the rest. We quote a fixed price after the plan, and standard migrations off BigCommerce are free with a new build or a twelve-month program.

Yes. Custom features are documented and rebuilt on the new platform's model (apps, metafields, or custom code), and integrations (ERP, email, search, subscriptions, POS, feeds) are reconnected or rebuilt against the new APIs and tested with real data before cutover. Nothing is assumed to port; the inventory decides what is kept, replaced, or retired.

Yes. The new store is built and loaded on staging while the old one keeps trading; a final delta sync of orders and customers runs at cutover, and the old store stays in read-only mode afterward for reference. Downtime at launch is minutes, not days.

Platform migration moves the store to a new system; data migration moves the records (products, customers, orders, content) accurately; website migration changes the site itself (domain, URLs, HTTPS, merged sites, architecture). Most projects combine all three, and the plan treats them as one program with one redirect map.

Thirty days of daily monitoring of crawl errors, 404s, rankings, speed, and conversion against the pre-migration baseline, bugs fixed as they appear, and a handover of documentation and credentials. Many clients keep us on for SEO, marketing, or a support plan, which is how a migration turns into growth rather than a one-time project.
