Shopify Migration

Migrate to Shopify without losing data, revenue or search visibility

Replatforming goes wrong when it's done blind. We move your catalogue, customers, orders and SEO to Shopify or Shopify Plus on a tested, reversible plan, so nothing important gets left behind on the old platform.

Why businesses migrate to Shopify

Most migrations aren't about chasing a trend. They're about escaping a platform that's costing more to run than it returns.

High maintenance cost

Hosting, security patches and developer retainers keep climbing while the store gets no faster.

Hard to manage

Everyday tasks like editing a page or launching a promotion need a developer instead of your team.

Slow development

Simple changes take weeks. The platform fights every new feature you try to ship.

Plugin conflicts

A stack of extensions that break each other on every update and slow the whole site down.

Weak scalability

Traffic spikes at sale time expose limits the platform was never built to handle.

Poor checkout

A clunky, low-converting checkout you can't fix without heavy custom work.

Limited international

Multi-currency, multi-language and market-specific pricing are painful or impossible.

Integration overhead

Keeping ERP, 3PL and POS connected is a constant maintenance burden.

Platforms we migrate

Every source platform carries its own risks. These are the migration paths we run most often, each with a dedicated approach.

WooCommerce to Shopify

WordPress stores on WooCommerce

Plugin sprawl and custom post types that don't map cleanly to Shopify's data model.

ScopeProducts, variations, customers, orders, blog posts, URL structure, reviews.

WooCommerce migration

Magento to Shopify

Magento 1 & Adobe Commerce merchants

Complex attribute sets, multi-store views and heavy custom extensions to unwind.

ScopeConfigurable products, customer groups, order history, CMS pages, SEO URLs.

Magento migration

BigCommerce to Shopify

BigCommerce merchants

Option sets, faceted URLs and native features that need Shopify equivalents.

ScopeProducts, variants, customers, orders, redirects, metafields.

BigCommerce migration

Salesforce Commerce Cloud to Shopify

SFCC & Demandware enterprises

Proprietary data model, deep integrations and enterprise catalogue scale.

ScopeCatalogue, price books, customer records, order history, content assets.

Salesforce Commerce Cloud migration

PrestaShop to Shopify

PrestaShop store owners

Combination-based variants and deep category trees that need remapping.

ScopeProducts, combinations, customers, orders, CMS pages, 301 redirects.

PrestaShop migration

Custom platform to Shopify

Bespoke or legacy in-house builds

No standard export. Data lives in a custom database or API with its own quirks.

ScopeExtracted by database export or API, then mapped to Shopify's schema.

Migration risk assessment

These are the five failures that cost merchants revenue during a migration, and how we control each one before cutover.

Risk	Potential impact	How Nexly controls it
Missing redirects	Rankings and referral traffic collapse as old URLs return 404s.	Full URL crawl and a 301 map for every indexed page, tested before launch.
Incorrect data mapping	Variants, prices or inventory land wrong and break listings.	Field-by-field mapping with sample migrations and reconciliation checks.
App incompatibility	Subscriptions, reviews or bundles stop working after cutover.	App audit up front; Shopify equivalents scoped or rebuilt before go-live.
Tracking failure	Analytics, pixels and attribution go dark on the busiest day.	GA4, GTM and ad pixels re-implemented and validated in staging.
Inventory mismatch	Overselling or phantom stock as data syncs mid-migration.	Delta sync at cutover so inventory reflects live stock at go-live.

SEO migration framework

SEO is where migrations most often go wrong. This is the framework we run on every replatform to hold rankings and traffic through the move.

Crawl & analysis

Internal-link updates
Structured data validation

Post-launch error & 404 checks

What gets migrated

Standard records map across automatically. Items like store credit, reviews, subscriptions and custom metafields usually need scripting. We identify these in discovery and scope them before we start.

Catalogue

Products
Variants & options
Product images & media
Collections & categories

Customers & orders

Customer accounts
Full order history
Product reviews
Gift cards & store credit
Discounts & codes

Content & SEO

Blog posts
Pages
Metafields
SEO metadata
301 redirects

How we run a migration

Every migration is scoped after discovery. We don't quote fixed timelines before we've seen the platform and the data. A typical build runs 6 to 10 weeks; migration complexity can move that either way.

Audit & architecture

We inspect your current platform, catalogue, integrations and traffic, then design the Shopify information architecture and URL structure.

Design & build

Theme and templates built to your brand, or a like-for-like rebuild, on Online Store 2.0 or Hydrogen.

Data mapping & integrations

Every field mapped source to Shopify. Apps, ERP, payments and shipping reconnected and tested.

Testing

Sample migrations, QA against the live site, checkout and payment testing, redirect and tracking validation.

Delta migration & launch

Final data sync, content freeze, DNS cutover and a staged redirect release with the team on standby.

Monitoring

Search Console, error logs and analytics watched closely through the first weeks after launch.

Launch & rollback plan

Cutover is the riskiest hour of any migration. We run it to a documented plan with clear rollback criteria, so if anything looks wrong we can step back safely.

DNS prepared and TTL lowered ahead of cutover
Content freeze on the old store to lock the dataset
Final delta sync of orders, customers and inventory
Live payment and checkout testing before traffic switches
Staged 301 redirect release and verification
Analytics, pixels and tag validation on the live domain
Real-time error and 404 monitoring after launch
Defined rollback criteria and a tested fallback path
Hands-on support through the stabilisation window

What shapes migration investment

Two things move a migration quote: how much data you're bringing across and how clean it is. Typical AU ranges:

Source platform and how cleanly it exportsRecord volume across products, variants, customers and ordersData quality and how much cleanup is neededNumber and complexity of integrations (ERP, 3PL, POS)Custom features to rebuild (subscriptions, bundles, B2B)Design scope, from like-for-like rebuild to full redesignSEO risk and redirect complexityInternational needs (multi-currency, multi-language, markets)B2B and wholesale requirements

Migration questions, answered

Yes. We migrate historical orders and customer records so support, returns and lifetime-value data carry over. Very large histories are migrated in batches and reconciled against the source. Some platforms limit what can be exported, which we flag in discovery.

No. Passwords are hashed and can't be moved between platforms. Customer accounts migrate, but shoppers reset their password on first login. We can trigger a branded reset flow at launch so returning customers aren't left confused.

Migrations carry SEO risk, but a well-run one protects rankings. We crawl every indexed URL, build a complete 301 redirect map, migrate metadata and monitor Search Console after launch. Short-term fluctuation is normal; the aim is to hold traffic and recover fast.

Typically none. We build and test on a separate Shopify store, then cut over by switching DNS, so the storefront stays live throughout. There's a brief content freeze so no new orders are missed during the final data sync.

Where a Shopify equivalent exists, yes. ERP, 3PL, POS, accounting and email tools reconnect during the build. Anything without a native option is rebuilt or replaced with a mapped alternative, scoped in discovery so there are no surprises at launch.

Subscriptions need care, because payment tokens and billing schedules don't always transfer cleanly. We plan the subscription migration up front, work with your payment gateway, and test billing before cutover to avoid failed or duplicated charges.

Usually yes. Reviews can be exported and imported into your chosen Shopify reviews app, preserving star ratings and content. The exact fields depend on your current and future review tools, which we confirm during scoping.

Yes. We keep the source platform accessible read-only after launch so you can reference historical data and verify the migration. We agree a decommission date once you're confident everything has moved across correctly.

We do, with your sign-off. We prepare DNS ahead of time, lower TTLs and coordinate the switch at a low-traffic window. If your domain sits with a specific AU registrar, we'll walk your team through the exact changes or make them with delegated access.

We monitor errors, 404s, analytics and Search Console through the stabilisation window and fix issues quickly. From there you can move onto a support retainer for ongoing development, CRO and performance work, or hand back to your internal team.
