Migration · OpenCart → Shopify

OpenCart was free. Free is now the most expensive option.

Self-hosting, security patches, version upgrades, broken extensions on every PHP bump. We move OpenCart stores to Shopify so you can stop running an IT shop on the side.

Why brands leave OpenCart

OpenCart's open-source promise looked great when you started, own your code, customise anything, no SaaS fees.

Five years later you're paying a developer on retainer to keep extensions compatible, hosting bills creep up as the catalog grows, and a routine PHP upgrade can break the cart for a weekend. The "free" platform turned out to have a real cost; it just shows up in your dev calendar instead of your subscription bill.

  • Self-hosting means PCI compliance, security patches, and uptime are your team's problem.

  • Extension compatibility breaks every major OpenCart and PHP release.

  • The marketplace is uneven, many extensions are abandoned or rarely updated.

  • Mobile speed scores are typically poor without significant theme work.

  • Multi-store and multi-language work but require careful manual configuration.

OpenCart-specific gotchas

What actually breaks when you migrate.

Most migration vendors quote a price and stay vague on what's hard. These are the OpenCart-specific traps and how we handle each one.

  • OpenCart's vQmod / OCMod modifications don't transfer.

    How we handle it →
    We document every active modification, decide what becomes a Shopify app vs. a theme customisation vs. a Function, and rebuild on the Shopify side rather than porting code.

  • Multi-store setups (one OpenCart admin, many storefronts) need re-architecting.

    How we handle it →
    We move each storefront to a Shopify Markets region or a separate Shopify store under one Plus org, with a shared customer database where possible.

  • OpenCart's product attributes use a flexible but unstructured model.

    How we handle it →
    We map attributes to Shopify metafields with proper types, so theme blocks read them correctly and Search & Discovery can filter on them.

  • OpenCart URLs (`index.php?route=product/product&product_id=42`) and SEO URLs both need redirecting.

    How we handle it →
    We export every product, category, manufacturer, and information URL, both pretty and parameterised, and stage 301 redirects for the lot.

  • Customer password hashes are OpenCart-specific.

    How we handle it →
    Customers reset on first login; we preserve email and order history and pre-stage the reset email so it's a one-click flow.

Data we preserve

Your customers, orders, SEO, nothing left behind.

  • Products with options, variants, custom attributes

  • Categories with images and SEO settings

  • Manufacturers

  • Customer accounts and customer groups

  • Order history with statuses, totals, fulfilment

  • 301 redirects for every URL, pretty and parameterised

  • SEO metadata, structured data

  • Coupons, vouchers, and discount rules

  • Reviews

  • Information / CMS pages

OpenCart feature → Shopify equivalent

Every feature has a Shopify-side answer.

The thing most migration vendors leave vague: which Shopify app, theme, or Function replaces each piece of your existing stack. We tell you in week one.

OpenCart Shopify equivalent
vQmod / OCMod modifications → Shopify Functions, theme app extensions, or app blocks
OpenCart multi-store → Shopify Markets / multi-store on Plus
Custom shipping rules → Shopify Functions + carrier-calculated rates
Manufacturers section → Shopify metaobjects + manufacturer pages
OpenCart filters / layered nav → Shopify Search & Discovery filters via metafields
Native blog (or extension) → Shopify Blogs (built in)
OpenCart email templates → Shopify Email + Liquid notification templates
How the migration runs

A staged migration. Not a weekend sprint.

3-5 weeks of structured work, discovery, scripts, theme rebuild, redirect map, UAT, launch. Every phase has a deliverable you keep.

  1. 01, Modification + extension audit

    Every vQmod, every OCMod, every active extension catalogued and mapped to a Shopify equivalent. Sign-off before scripts run.

  2. 02, Theme rebuild on Online Store 2.0

    We rebuild your storefront with section-based architecture and Core Web Vitals targets. Mobile speed jumps from "needs work" to "good" in nearly every migration.

  3. 03, Data migration scripts

    Products, attributes, customers, orders, manufacturers, reviews migrated via custom scripts. Validated on a Shopify dev store before cutover.

  4. 04, URL map + SEO transfer

    301 redirects for both pretty and parameterised URLs. Metadata preservation. Structured data carried over.

  5. 05, Test launch

    Password-protected staging where your team runs full checkout, abandoned cart, fulfilment, and email flows.

  6. 06, Launch + 30-day stabilisation

    DNS cutover with monitoring on 404s, organic traffic, conversion, and integration health for 30 days.

The trade is simple: stop owning the infrastructure problem, get a faster store, redirect the dev budget into things that actually move revenue.

What we keep, what we rebuild

Keep: products, customers, orders, reviews, blog content, SEO equity.

Rebuild: theme (OpenCart’s templates don’t translate to Liquid), modifications (we map each to a Shopify mechanism), multi-store architecture (we use Markets or separate stores under one org).

What we don’t do

  • We don’t port vQmod / OCMod code directly. The architectures are too different to bridge cleanly.
  • We don’t recommend a migration if your store is sub-$100k/yr and your OpenCart isn’t actively breaking, at small scale the friction outweighs the upside.
  • We don’t carry over OpenCart’s URL structure. 301 redirects do the SEO work; the new URLs are cleaner.

OpenCart migration FAQ

Common questions about OpenCart → Shopify.

We have many active OpenCart modifications. Will they all be replaced?

Most yes, some no. We catalogue every modification in week one and tell you up front which Shopify covers natively, which has a clean app equivalent, and which (if any) need custom Shopify Functions work.

Can multi-store OpenCart move to Shopify?

Yes. Single-brand multi-region goes to Shopify Markets. Multi-brand goes to separate Shopify stores under one Plus org. We design the architecture in week one.

How much does our hosting cost change?

Goes to zero. Shopify includes hosting, CDN, security patching, PCI compliance, and 99.99% uptime. The dev retainer line item usually shrinks too.

What about our customisations?

We don't port them code-for-code. We catalogue what they do, map each to the right Shopify mechanism (Function, app, theme block), and rebuild. The result runs faster and survives future Shopify updates.

Will my SEO survive?

With our 301 redirect map (covering both pretty and parameterised URLs) and metadata preservation, organic traffic typically recovers within 4 weeks.

What's the cost?

Every migration is quoted after a free audit, typical OpenCart projects save up to 70% versus a like-for-like quote on platforms with revenue-tier pricing. Multi-store, B2B, and rule-heavy migrations are scoped individually.
