OpenCart migration to a modern headless stack

OpenCart is easy at first, but it’s aging: an uneven extension ecosystem, limited scaling and poor performance on large catalogs. We move you to Sylius/Symfony + Next.js.

Why migrate off OpenCart

Extension quality varies a lot, updates are risky, and at higher traffic and larger catalogs performance and maintenance become real problems.

What’s specific about migrating off OpenCart

OpenCart often comes with extensions (OCMOD/vQmod) and core modifications that are hard to maintain, plus old PHP versions. We extract the catalog, attributes, customers and orders from the OpenCart database, document what the extensions do and rebuild only what’s needed, cleanly, in a modern architecture.

  • Catalog and attributes extracted from the OpenCart DB
  • OCMOD/vQmod extensions assessed and rebuilt only when needed
  • Escape core modifications and old PHP

What you gain

A mature, extensible e-commerce core, a fast frontend and an architecture you can extend without relying on questionable extensions.

Migration steps

  1. 1

    Audit & inventory

    We analyze your OpenCart store: catalog, categories, URLs, integrations (couriers, invoicing, marketplace feeds), traffic and pain points. We set measurable goals.

  2. 2

    Migration plan & architecture

    We propose the headless architecture (Sylius/Symfony + Next.js), the data migration plan and the SEO strategy to keep your rankings. You get a clear estimate and timeline.

  3. 3

    Data export & mapping

    We export products, categories, customers and orders from OpenCart and map them into the new data model, with integrity checks.

  4. 4

    Backend + frontend development

    We build the Sylius/Symfony backend and the Next.js frontend, with incremental deliveries and a staging environment you can test.

  5. 5

    SEO: URL mapping + 301 redirects

    We map all old URLs 1:1 and set up 301 redirects. The stated goal: zero organic-traffic loss, tracked in Search Console after launch.

  6. 6

    Launch & optimization

    A controlled cutover with real-time monitoring (goal: zero downtime), then continuous optimization and subscription maintenance.

Frequently asked questions

Extension quality varies a lot, updates are risky (especially with core modifications), and at higher traffic and larger catalogs performance and maintenance become real problems. A modern stack fixes that.

We assess what functionality they provide and rebuild it natively or via dedicated integrations, without depending on questionable extensions.
