What a Shopify migration actually is
A platform migration is not a redesign. It is moving a live commercial operation from one technical foundation to another while keeping orders flowing, rankings intact and customers unaware anything changed. Shopify specifically has its own data model, its own checkout, its own app ecosystem and its own constraints. Moving to or from it touches every part of the stack.
Most teams underestimate two things: the depth of the integration work, and the SEO risk. The build itself, themes, content, catalog structure, is the visible part. What sits underneath is usually where projects run long.
Inbound or outbound, decide the direction first
Before planning the migration, be honest about why you are moving. The most common scenarios:
Magento to Shopify Plus. Often driven by operational cost, team capacity or a desire to move away from self-hosted infrastructure. Shopify Plus handles the hosting, security and core commerce. The trade-off is less customisation depth and a different data model. If your Magento store leans heavily on custom modules, part of the migration is deciding what to keep, rebuild differently, or abandon.
WooCommerce to Shopify. Typically a scale question. WooCommerce works well up to a point. Beyond that, checkout stability, app conflicts and performance become ongoing problems. The migration is usually simpler than Magento because the underlying data is less complex.
Shopify to Shopware or Norce. Usually driven by B2B requirements that Shopify Plus cannot handle cleanly. Customer-specific pricing tied to an ERP, deep catalog complexity, quote flows, multi-warehouse inventory, or a need for more architectural control. See the B2B ecommerce guide for when this trade-off tips.
Shopify to headless. A different question again. Keeping Shopify as the commerce backend but moving the frontend to a custom build or headless architecture. Not a full migration, but has many of the same risks around SEO and integration continuity.
The five things that drive the scope
1. Catalog complexity. How many products, how many variants, how deep the attribute model. Simple D2C catalogs migrate in weeks. Configurable products, bundles, multi-warehouse inventory and localised content add months.
2. Integrations. Every connected system (ERP, PIM, marketing, fulfilment, customer service) is a separate migration project. Shopify's app ecosystem is large but opinionated. Integrations often need to be rebuilt rather than ported. See our ERP integration guide for deeper context.
3. Checkout. Shopify's checkout is locked down. Custom checkout logic from Magento or a headless setup usually needs to be redesigned within what Shopify Plus allows. For B2B checkout with invoice, PO numbers and approval flows, Briqpay and similar providers integrate with Shopify, but the flow is different.
4. Content and SEO. Product content, category pages, blog posts, URL structures, structured data. Migration without a URL redirect map is where rankings die. Every indexed URL on the old store needs a planned destination on the new one.
5. Customer data. Accounts, order history, loyalty points, subscription state, saved carts. Customers notice when their history disappears. Planning customer data migration (and communicating it) is often treated as an afterthought.
Data migration, where the time actually goes
Data migration breaks down into four layers:
Products. The catalog itself. Usually straightforward for simple products, harder for configurable products, variants with custom attributes, and products with complex relationships (bundles, kits, cross-sells). Shopify's product model is flatter than Magento's, so mapping is a translation exercise, not a copy.
Customers and orders. Customer accounts with hashed passwords cannot be migrated without a password reset flow. Order history migrates as historical data. Customers see it, but it does not behave as native Shopify orders (returns, reorders, loyalty) unless specifically rebuilt.
Content. Category descriptions, blog posts, landing pages, metadata. Shopify's CMS is lighter than Magento or a dedicated headless CMS like Storyblok. For content-heavy sites, a headless setup with Shopify as commerce and Storyblok as CMS is often the better endpoint.
SEO data. This is the layer most commonly broken. URL structure, redirects, canonical tags, structured data, hreflang for multi-market. A redirect map covering every indexed URL is non-negotiable.
Integration continuity
A migration is only as successful as the integrations that follow. The typical integration checklist:
Payment. Shopify Payments is the native option and handles most needs for D2C. For Nordic markets, Klarna, Svea, Walley, Adyen and Mollie all integrate. For B2B with invoice, Briqpay is purpose-built. Which provider fits depends on markets, payment methods and reconciliation needs, not on a single universal recommendation.
ERP. Shopify connects to most Nordic ERP systems including Business Central, Fortnox and Visma.net. The integration pattern is different from Magento. Typically via a middleware layer rather than direct. Real-time stock and pricing requires planning.
Shipping. Ingrid and nShift are the Nordic defaults and integrate with Shopify. The delivery checkout experience is often re-designed during migration. Worth doing deliberately rather than as a last-minute item.
Marketing and CRM. Klaviyo is the standard for Shopify email and SMS. Customer sync needs to be re-established, historical data imported, and flows rebuilt.
SEO, the migration task that must not fail
If a migration ships with broken URLs, missing redirects or mangled structured data, organic traffic collapses. Recovery is possible but takes months and is never complete. The work to avoid this is unglamorous and must not be skipped.
Export every indexed URL from the current store. Map each one to its destination on the new store. Set up 301 redirects at the server level before launch. Preserve canonical tags, structured data and hreflang exactly. Validate in Search Console post-launch for crawl errors, index coverage and ranking drops. Monitor daily for the first month, weekly for the next two.
This is where a phased launch pays back. A soft launch on a fraction of traffic lets you catch SEO regressions before they hit rankings.
Launch, phased beats big-bang
The safest migration pattern is phased: soft launch with controlled traffic, validation window, full cutover. Running the old and new stores in parallel for a short period, same catalog, same pricing, small traffic split, lets you validate orders, integrations and performance with real load before committing.
Big-bang migrations work when scope is small and integrations are simple. For anything involving ERP, large catalogs, or significant SEO, phased launch is worth the extra cost.
When Shopify is not the right answer
Shopify Plus is the right platform for a large share of merchants. It is not the right platform for all of them. The cases where Shopware, Norce or headless usually win:
Deep B2B with customer-specific pricing tied to an ERP, multi-level approval flows, quote management, or complex account hierarchies. Shopify Plus B2B has grown significantly but still has ceilings here.
Multi-warehouse inventory with real-time allocation across locations, split shipments, and warehouse-specific pricing. This is Shopware and Norce territory.
Catalogs with thousands of configurable products, technical attributes, or deep variant matrices. PIM integration is possible on Shopify but the catalog experience is more native on Shopware.
Content-heavy sites where editorial, product and commerce need to work together. A headless setup with Storyblok plus Shopify (or Norce) often delivers better than Shopify alone.
What a migration project costs
A straightforward D2C migration to Shopify Plus with standard integrations typically starts around €30,000 to €60,000. A migration with full ERP integration, complex catalog, B2B requirements or multi-market scope generally runs €80,000 to €200,000. The Shopify Plus licence itself is separate and priced on revenue.
The cost driver is almost always integration depth and data complexity, not the Shopify build. Contact us for a scoping conversation tailored to your current setup.
