Online store migration to a modern headless stack

We move your store off any popular platform — WooCommerce, PrestaShop, OpenCart, Shopify, Magento, MerchantPro or Gomag — to a modern headless stack: Sylius/Symfony on the backend and Next.js on the frontend. We preserve SEO, URLs and order history.

What the architecture looks like

From your current platform to your customers

Where we start

Your current platform

  • WooCommerce
  • PrestaShop
  • Magento
  • Shopify
  • OpenCart or another

The store engine

Sylius / Symfony

  • catalogue and stock
  • orders and payments
  • customers and accounts
  • integrations: ERP, couriers, invoicing

The storefront

Next.js

  • fast pages
  • SEO: URLs and indexable content
  • Core Web Vitals

Where the pages land

Your customers

  • phone
  • desktop
  • Google
The migration flow: data from the current platform (WooCommerce, PrestaShop, Magento, Shopify or another) moves into Sylius / Symfony — catalogue, orders, customers, integrations —, Next.js builds the fast pages, and customers find them on phone, on desktop and in Google.

Start with the migration audit

A full migration is a big decision, and a quote given without looking inside your store is guesswork. The migration audit turns “what would it cost?” into a number you can rely on — one you can take to any vendor, even if you don’t work with us.

from 1,500 lei + VAT5 working days

Prices exclude VAT (21%). SISSOFT GLOBAL SRL is VAT-registered.

  • Start for free: we look at 3 pages (homepage, one product, the checkout) and send you the first 5 issues within 2 working days. Only then do you decide whether you want the full audit.
  • Our first 3 audit clients pay after the 30-minute session in which we walk through the report together. If the report showed you nothing you didn't already know, you don't pay.
  • The audit is fully deducted from the implementation price.

When a migration makes sense

If your store has outgrown the platform it started on — large catalog, growing traffic, poor mobile speed or rising costs — a migration to headless gives you back control over performance and cost.

  • Catalogs with thousands to hundreds of thousands of products
  • Poor mobile Core Web Vitals
  • Slow, hard-to-extend admin
  • Rising infrastructure costs

How we protect SEO during migration

We map all old URLs 1:1, set up 301 redirects and preserve the content structure. We migrate products, categories, customers and orders with integrity checks, and launch through a controlled cutover.

Migration steps

  1. 1

    Audit & inventory

    We analyze your current 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 your current platform 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

No, if done correctly: full URL inventory, 1:1 mapping, 301 redirects and post-launch monitoring. That’s how we migrated electronic-mag.ro (351,000+ products), with Search Console monitoring after launch.

From WooCommerce, PrestaShop, OpenCart, Shopify, Magento, MerchantPro and Gomag — to a modern headless stack (Sylius/Symfony + Next.js). We have dedicated pages for each.

Yes. We migrate products, categories, customers and order history, with automated integrity checks at every step.

It depends on catalog size, integrations and historical-data migration. We start with the migration audit, which begins at 1,500 lei + VAT and gives you a firm estimate and timeline — and is deducted in full from the project price if you go ahead.
