How does a shop migration to Shopware 6 work?

A shop migration is more than a technical update: product data, customer accounts, order history, design and search engine rankings all have to survive the system change unharmed. With a structured approach this is very manageable – the key is to identify the critical points early. As a Shopware agency we work with a proven phase model for this.

The trigger is often the end of support for a legacy system – such as Shopware 5, whose official support has ended – or grown requirements that the existing system can no longer handle. Whatever the reason: a migration is a good opportunity to scrutinise data quality, processes and design instead of carrying legacy issues over one to one.

The typical project phases

1. Analysis and planning: Inventory of the legacy system, data structures, plugins, integrations and URLs. This produces the migration concept, a realistic schedule and a prioritised feature list.
2. Building the new shop: Setting up Shopware 6, implementing the theme, configuring payment methods, shipping rules and taxes, and developing the required extensions on a staging environment.
3. Data migration: Transferring products, categories, customers and orders – using the Shopware Migration Assistant for standard cases and tailor-made scripts for custom data structures. Several trial runs safeguard data quality.
4. Testing and SEO preparation: Functional tests, test orders, performance checks and a complete redirect plan from old to new URLs so that rankings are preserved.
5. Go-live and aftercare: Switching the domain, final data synchronisation, monitoring during the first days and prompt fixes if anything unexpected occurs.

The critical points: data and SEO

In our experience, data migration is the heart of the project. The Shopware Migration Assistant covers standard cases; custom fields, complex product structures or historical data, however, often require dedicated migration scripts and several test runs. Just as important is the SEO migration: if URLs change without clean 301 redirects, rankings built up over years can be lost. A complete URL inventory and a redirect concept therefore belong in every migration project.

The system landscape also needs attention: connections to ERP, inventory management, payment providers and shipping carriers have to be set up again or adapted in the new system. Thanks to the API-first architecture of Shopware 6, existing integrations can often even be improved in the process – for example through shorter synchronisation intervals or cleaner error handling. Plan these connections early, as the third-party providers involved often have lead times of their own.

A migration can also be prepared well on the shop owner's side: clean up your product data before the transfer instead of carrying over outdated articles, duplicates and unmaintained categories. Clarify early which plugins of the legacy system are actually still needed – in our experience, a portion of them is dispensable or already core functionality in Shopware 6. And define measurable acceptance criteria, for example which test orders must complete successfully before go-live. This shortens the test phase and reduces surprises after the switch.

Throughout the entire project, the existing shop stays online – sales continue without interruption. The duration depends on the scope: smaller shops with standard functionality are migrated considerably faster than complex projects with many custom developments and integrations. You will receive a reliable schedule after the analysis phase; how we structure projects in general is shown in our project process.
