Inconsistent data
Different fields, missing IDs and incomplete records

Moving from Magento, Gambio, JTL, OXID or WooCommerce to PrestaShop, Shopify or Shopware? We handle your migration with careful data planning, security and search visibility in mind.
The market has changed significantly in recent years. Rising subscriptions and additional monthly module fees have, for example, made Shopware less economical for many retailers.
Moving from Shopware 5 to 6 also requires a complete rebuild, including system assessment, design adaptation and replacement modules.
For many retailers, this is a reason to reconsider the platform strategically: PrestaShop can be a particularly economical choice, while Shopify offers a modern SaaS solution with manageable implementation effort.
Projects on Magento, WooCommerce, Gambio, JTL and OXID can also reach technical, financial or maintenance limits.
Switching systems takes work, but can create an opportunity for better processes, lower running costs and a store that fits both current and future plans.
Different fields, missing IDs and incomplete records
Incorrect redirects, changed URLs and ranking drops
Shipping, payments and ERP often cannot be transferred unchanged
Migration without thorough testing can cost sales
Functional differences between systems, for example in B2B features
Without sound knowledge of both source and target systems, mistakes can lead to data loss or additional costs.
Switching ecommerce platforms means more than copying product data.
Every migration is an individual project, with dependencies, specific requirements and risks.
We therefore handle the entire process, covering technology and structure in close coordination with you.
Assess source and target systems, integrations, requirements and SEO structure
Products, categories, customers, orders, content, media and URL structure
Connect shipping, payment methods, ERP, inventory, newsletters and tracking
Use targeted redirects and canonical URLs to reduce ranking-loss risks
Functional tests, a sandbox, final checks and a controlled launch
Launch follow-up, fine-tuning and technical support for the live store
We migrate stores from different technical environments, whether changing platforms entirely or upgrading within the same system. Our approach is structured and data-led, whatever the age or complexity of your existing store.
These examples show common platform changes. Whatever your current system, we plan a safe, considered migration.

Every sector has its own characteristics, and that is what we enjoy.
From fashion start-ups to international spare-parts retailers, we support clients technically and strategically, reliably and over the long term. Here is a small selection of our projects:

















For Bildhau KG, we migrated PrestaShop from version 1.7 to 8.1 and modernised the technology. Alongside transferring relevant data and settings, we focused on improving search-related areas.
Existing modules were updated and extended to cover current requirements. We also fully adapted and integrated the Logiflex interface to support communication with logistics providers.
The result is a faster, more stable system with an improved SEO structure, greater flexibility for extensions and noticeably lower ongoing maintenance effort.

The move from Shopware 5 to PrestaShop followed steadily rising subscription and module licensing costs.
We migrated all core data: customers, orders, products and categories. The existing design and content were also carried over faithfully.
A central module provided the direct Amazon connection, integrating marketplace sales.
The new platform provides a scalable foundation with control over functions and extensions, while substantially reducing ongoing costs.

The existing VISMA ERP import module had reached its technical limits and needed substantial redevelopment. The client also needed an efficient way to import all product images in bulk.
We redesigned the module around the client’s specific requirements. For image imports, we developed a dedicated solution that automatically processes and reliably imports all product images.
VISMA ERP and PrestaShop now work smoothly together, with substantially lower ongoing costs and improved sales reporting. A light design refresh created a more usable, contemporary B2B shopping experience.

For a specialist B2B store, we developed a concept in which prices and ordering are available only after registration and business verification. Training sessions also needed booking with deposits, supported by an integrated live-shopping feature.
We implemented this in PrestaShop using suitable modules for automated checks and access restrictions. Klaviyo handles email marketing, while Channelize provides the connection for future live-shopping events.
The result is a capable platform designed for B2B sales and relevant legal requirements. Automated workflows, scalable sales functions and a professional marketing setup support efficiency, reach and measurable results.

It depends on data volume, the target system and any integrations. Smaller migrations take a few days; complex projects can take several weeks.
We pay attention to URL structures, permanent (301) redirects and canonical URLs to protect visibility and reduce losses. Unchanged rankings cannot be guaranteed.
We migrate this data, including categories, variants, customer details, order history, reviews and more.
Yes. We integrate existing systems or replace them with suitable alternatives. Third-party inventory and CRM software can also be connected.
We assess the source and target systems, run tests, prepare the data and support the launch. The entire process is structured and documented.
We work in a development environment. The switch is coordinated to minimise downtime and disruption for your customers.
