SHOPIFY MIGRATION
Shopify Migration: Move to Shopify Plus from WooCommerce, Magento or BigCommerce
A Shopify migration should be more than moving your store from one platform to another. We move your products, customers, and order history, protect your SEO and redirects, and rebuild your store around conversion. So when you launch on Shopify, you are not starting over with the same store. You are launching with a store optimised for conversions.
At Conversion Design, we don't just migrate your data. Every Shopify migration includes a new Shopify Plus store built with our CRO process. You keep your products, customers, order history, and SEO structure while moving to a faster, conversion focused store.

Successful Migrations
WooCommerce, Magento and BigCommerce stores moved to Shopify Plus, each one including a conversion-designed new store rather than just a data transfer.

Loading On Every Build
Every migrated store is built and tested for fast loading on mobile, because speed is conversion, especially on a phone.
No data lost
Products, Customers, Order History
Products, customers, order history and SEO structure all move across. Nothing is left behind and every old URL is mapped before launch.
Zero
Downtime During Launch
Zero-downtime DNS cutover during low-traffic hours. No lost orders, no broken checkout, no disruption to your customers.
(01) OVERVIEW
Why migrate to a conversion-designed Shopify Plus store?
Most Shopify migrations are treated as data transfers: move the products, move the customers, and keep a similar design. That's a missed opportunity. Whether you're planning a WooCommerce to Shopify migration, a Magento to Shopify migration, or a BigCommerce to Shopify migration, you're already investing in a new platform. Why not use the opportunity to build a store that is designed to convert better?
At Conversion Design, we don't simply replicate your old WooCommerce theme or Magento template. We rebuild the store around our CRO process, with benefit-first product page design, friction-free ecommerce checkout optimisation, mobile-first UX, and fast loading times. The result is a faster, more scalable Shopify store with a strong focus on conversion.
This is what separates a Shopify Plus agency migration from a typical freelancer migration. You get the platform upgrade and the conversion rate upgrade in the same project.

(04) PROCESS
The Shopify Plus migration process
01
Discovery & Audit
We analyze your current WooCommerce, Magento, or BigCommerce platform, data structure, product catalog complexity, customer records, existing integrations (ERP, CRM, Klaviyo, reviews), and full SEO footprint including indexed URLs and backlink profile. We identify Shopify migration risks and map the highest-impact conversion opportunities for your new store.
02
Redirect Mapping
Every URL on your old site is mapped to its Shopify Plus equivalent. Category pages, product pages, blog posts and custom pages all get 301 redirects to preserve your hard-earned SEO authority and Google rankings. It is the most critical step in any Shopify migration, because a single broken redirect can cost you organic traffic.
03
Conversion-Designed Store Build
While the data migration is prepared in parallel, we design and build your new Shopify Plus store using our CRO process. Every product page uses benefit-first hierarchy, strategic social proof placement, and conversion-focused CTAs. Checkout is redesigned for friction-free completion with trust signals and progress indicators. Mobile-first ecommerce UX for the 70%+ of your traffic on mobile. Every build ships fast loading on mobile at launch.
04
Data Migration & QA
All products, variants, images, customer records, order history, and metadata are migrated to Shopify Plus. We run comprehensive QA, checking every product listing, every 301 redirect, every ERP/CRM/Klaviyo integration, and every payment/tax configuration across all markets. No data loss. No broken links. No surprises at launch.
05
Launch & Post-Migration Monitoring
Zero-downtime DNS cutover during low-traffic hours, your customers see no interruption. 48-hour post-launch monitoring of all redirects, checkout flow, and payment processing. Google Search Console and GA4 analytics verification to confirm SEO preservation.

Shopify Plus migration cost by platform
How much does a Shopify migration cost in 2026? Pricing depends on your source platform, data complexity, and how much conversion optimization you need in the new store. Below are the typical Shopify migration cost ranges we quote:
| PLATFORM | DATA MIGRATION | NEW STORE | TOTAL |
|---|---|---|---|
| WooCommerce to Shopify | €3K–€8K | €5.6K–€20K | €8.6K–€28K Shopify · €13K–€75K Plus |

Every Shopify migration includes 301 redirect mapping and SEO preservation. The price depends on how much data moves, how many integrations have to be rebuilt, and how much of the store is redesigned on the way, which is why we scope it after looking at your current setup rather than quoting a range up front.

Frequently asked questions about Shopify Plus migration
How much does a Shopify migration cost in 2026?
WooCommerce to Shopify migration costs €8,600–€28,000 (standard Shopify) or €13,000–€75,000 (Shopify Plus). Magento to Shopify migration costs €10,000–€45,000 or €20,000–€100,000 for Plus. BigCommerce to Shopify migration costs €8,100–€21,000 or €11,000–€65,000 for Plus. At Conversion Design, every Shopify migration includes a conversion-designed new store, not just a data transfer.
How long does a Shopify Plus migration take?
A standard Shopify migration takes 4–8 weeks. A full enterprise migration from Magento, with complex catalogue structures, B2B pricing and several integrations, runs longer. The schedule is usually set by how quickly product data and content are ready rather than by development, and the redirect mapping is finished before launch rather than after it.
Will I lose my SEO rankings when migrating to Shopify?
Not if the Shopify migration includes proper 301 redirect mapping. Every old URL is mapped to its new equivalent before launch, so links and rankings land where they should instead of on a 404. It is the single most critical part of the move, and the part most migrations get wrong, so it is scoped and checked before anything goes live.
Can I migrate from WooCommerce to Shopify Plus?
Yes, and it is the most common migration we run. Products and variants, customer records, order history, reviews and blog content all come across, and every old URL is mapped to its Shopify equivalent before launch so your rankings move with you. WooCommerce data tends to be the messiest part, because plugins store things in their own tables, so we audit what is actually there before we touch it and tell you what will not survive the move. Cost depends on how much data there is and how much of the store gets rebuilt on the way, so we scope it once we have seen your setup.
Do you build a new Shopify store during the migration?
Yes, every Shopify migration by Conversion Design includes a new Shopify Plus store rather than a copy of the old theme. You are already paying to change platform, so the templates are rebuilt with our CRO process: benefit-first product pages, a friction-free checkout and mobile-first UX. Every migrated store is built and tested for fast loading on mobile.
