BizTorq upgrades OpenCart 3 stores to OpenCart 4 and moves stores from Shopify and WooCommerce to OpenCart. Products, customers, orders and SEO URLs come with you, every old URL gets a 301 redirect, and your live store keeps selling until the switch.
OpenCart 4 brings a newer codebase, PHP 8 support and a cleaner admin, but it changed how extensions and themes are built. That is why there is no safe one-click upgrade. We set up a fresh OpenCart 4 store, move your data across, and rebuild your theme and custom modules for version 4.
Every installed extension checked: upgrade, replace or rewrite.
Your current design rebuilt for OpenCart 4, or refreshed while we're at it.
Server checked and updated so the new store runs fast and secure.
Businesses move from Shopify to OpenCart to stop paying monthly plan and app fees, to own their code and data, and to get B2B features like customer-group pricing and MOQ without paid apps. We export your products, variants, collections, customers and orders from Shopify and rebuild them in OpenCart. Shopify does not export customer passwords, so customers set a new password on their first login.
WooCommerce stores often slow down as the catalogue grows and plugins pile up. OpenCart is built only for eCommerce and handles large catalogues and wholesale pricing natively. We move products, attributes, categories, customers, orders and blog content from WooCommerce, and existing customer passwords can often be kept.
Names, descriptions, prices, variants, attributes, images, stock and categories.
Accounts, addresses and customer groups, including wholesale buyers.
Order history, statuses and the link to each customer.
Every old URL mapped to its new URL with a 301 redirect; titles and meta descriptions kept.
Information pages, blog posts and policies.
Taxes, GST, shipping rules, payment gateways and email templates set up again.
Your current store keeps taking orders while we build the new one on a staging server. Downtime is limited to the final switch.
Not with one click. OpenCart 4 changed the extension and theme structure, so we set up a fresh OpenCart 4 store, move your data into it, and rebuild or replace extensions and the theme for version 4.
Most will not work as they are. We check each extension: some have an OpenCart 4 version, some can be replaced, and custom ones are rewritten.
Not if URLs are handled properly. We map every old product, category and page URL to its new URL with a 301 redirect and keep titles and meta descriptions, so search engines pass the old rankings to the new pages.
From Shopify, yes — Shopify does not export customer passwords, so customers set a new one on first login. From WooCommerce or OpenCart 3, existing passwords can often be kept.
Yes. Past orders, order statuses and customer links are moved so customers and your team can still see their history.
It depends on product count, extensions and design changes. We give you a timeline after reviewing your current store.
Send us your store URL — we'll review it and tell you what moves, what needs rebuilding and how long it takes.
