Migrating to Shopify: approach, timeline and risks

A migration to Shopify touches more than just your product catalogue. Customer data, order history, content, URL structure and integrations all need to move across, without losing SEO rankings or customer trust. This article walks through the full approach: moving from WooCommerce, Magento or Lightspeed to Shopify, including timeline, risks and a practical checklist.

Which platforms migrations typically come from

• WooCommerce — the switch is often driven by admin overhead, hosting issues under peak load, or the lack of scalable app integrations.
• Magento — migration is usually prompted by high maintenance costs, outdated extensions, or a shortage of developers for the platform.
• Lightspeed — often a move towards international growth or more advanced marketing and app capabilities.
• Custom-built systems — migration here is mostly about reducing maintenance burden and no longer depending on a single developer or agency.

Each source platform has its own data quirks. Magento catalogues, for example, often contain complex attribute sets, while WooCommerce sites tend to carry many separate plugins with their own database tables. Map this out upfront — it determines migration complexity more than catalogue size does.

What exactly you migrate

Component	Watch out for
Products and variants	Attributes, stock statuses and variants don't always map 1-to-1 to Shopify's structure
Customer data	Passwords generally don't migrate; customers need to set a new one
Order history	Important for customer service and accounting, usually imported as an archive rather than active orders
Content	Blog posts, landing pages and product descriptions, including metadata
Reviews	Often a separate app migration, depending on your review platform
Discount codes and subscriptions	Require precise mapping so running promotions don't break
Redirects	The single most important step for preserving SEO value

301 redirects and SEO risk

Every URL that changes without a redirect costs you rankings and direct visitors clicking an old link. Shopify's URL structure almost always differs from your current platform (think fixed /products/ and /collections/ paths), so a complete redirect map isn't a nice-to-have — it's a mandatory part of every migration.

Practical approach:

1. Export every indexable URL from the current site (crawler + Search Console).
2. Map each old URL to its new Shopify URL, including category and filter pages.
3. Have 301 redirects ready before launch, not after.
4. Monitor for 404s via Search Console post-launch and fix gaps within days, not weeks.
5. Preserve the content and structure of pages with the most organic value as much as possible, rather than rewriting everything from scratch.

Don't underestimate this part: much of the traffic dip seen after migrations stems from missing or incorrect redirects, not from the platform itself. For the broader SEO approach on Shopify, see Shopify SEO.

Realistic timeline

Phase	Duration (indicative)	Contents
Discovery & scope	1-2 weeks	Data inventory, mapping integrations, requirements
Setup & theme	2-4 weeks	Theme setup, structure, configuring integrations
Data migration	1-3 weeks	Products, customers, orders, content, in parallel with the build
Redirect mapping & SEO check	1-2 weeks	Full URL mapping, metadata, structured data
Testing	1-2 weeks	Checkout flow, payment methods, shipping, email flows
Go-live & aftercare	1-2 weeks	Launch, monitoring, rapid fixes

For an average mid-size store, budget 6 to 12 weeks from kickoff to a stable launch. More complex projects with ERP integrations or multilingual catalogues can easily run to 4-6 months. See our guide to migration costs to align timeline and budget.

Data cleanup: do this before the migration, not after

A migration is the best moment for a clean sweep:

• Remove outdated products and duplicate SKUs.
• Consolidate customer data (duplicate accounts, stale email addresses).
• Reassess categories and filters — don't blindly copy an outdated structure.
• Check product images for resolution and naming.

Carrying unclean data across drags problems into the new platform and makes future optimisation harder.

Integrations: ERP, PIM and POS systems

Most migration projects don't fail on the platform itself, but on the integrations around it:

• ERP — stock, pricing and orders need to sync in real time or near-real time; test this thoroughly before launch.
• PIM — for large or complex catalogues, a PIM integration avoids manual product management inside Shopify itself.
• POS/checkout systems — important for physical stores; Shopify POS integrates tightly with the platform, external POS systems often require custom work.
• Accounting and fulfilment — check whether existing integrations have a Shopify version or whether an alternative is needed.

Testing and go-live checklist

• Full checkout flow tested, including every payment method
• Shipping methods and rates configured correctly
• All redirects live and verified as status 301 (not 302)
• Metadata (title, description) carried over or optimised
• Structured data (product, review) implemented correctly
• Email flows (order confirmation, shipping confirmation) tested
• Customer accounts and password-reset flow verified
• Analytics and tracking pixels installed correctly
• DNS and domain transfer scheduled during a quiet moment (not a peak)
• Backup of the old environment available for reference

Common mistakes that cost traffic

• Forgetting redirects for filter and category pages, which often rank well.
• Rewriting content too quickly instead of preserving and improving proven pages.
• Launching without 404 monitoring, so errors only surface weeks later.
• Underestimating internal link structure — old internal links point nowhere after migration.
• Testing payment methods too late, resulting in a broken checkout right after launch.

A well-executed migration doesn't have to mean a noticeable drop in organic traffic — but that requires upfront planning, not reactive fixes afterwards.

Frequently asked questions about migrating to Shopify

How long does a migration to Shopify typically take?

For a mid-size store, 6 to 12 weeks. More complex projects with multiple integrations or languages can extend to several months.

Will I lose my Google rankings during a migration?

Not necessarily, provided redirects, content and structured data are carried over carefully. Most traffic losses stem from missed redirects, not from the platform itself.

Do customer passwords migrate automatically?

No, this is technically and for security reasons impossible on virtually every platform. Customers set a new password on their first visit.

Can I keep my ERP integration after migrating to Shopify?

Often yes, but the integration usually needs to be rebuilt for Shopify's APIs. Check this early in the project, not during the build.

What does a migration to Shopify cost?

This depends on catalogue size and integrations; budget €5,000-40,000. See the full breakdown under Shopify costs.

Is Shopify a suitable alternative to my current platform?

For most standard e-commerce processes, yes. If you're unsure whether Shopify fits your situation, check our Shopify alternatives or get in touch for tailored advice.
