PrestaMigrate to PrestaShop 9.1 without losing your orders or SEO
Staying on PrestaShop 1.6, 1.7, or an unsupported version 8 means mounting security vulnerabilities, PHP 8.3 compatibility issues, and abandoned modules. We migrate your store to PrestaShop 9.1, the latest major release, with a detailed go-live plan, 301 redirects, and a rollback option.
- Module-by-module compatibility audit, with a full quote before work begins
- Complete data migration: customers, orders, invoices, products and stock
- Full 301 redirects to preserve your existing SEO rankings
- Go live in under an hour, during off-peak hours, with a rollback plan
Our 6-step migration process
No migration starts without an audit and a quote approved by you.
1. Existing store audit
A full audit of your modules, theme, overrides, custom developments and data volumes. The result: a fixed quote and a list of potential breaking points.
2. Accurate staging environment
A complete copy of your store is migrated to an isolated test environment, using the same data and target hosting setup.
3. Data migration
Customers, orders, invoices, products, combinations, stock, promotions and CMS content are migrated, then verified through record counts and sampling.
4. Modules and custom development
Every module is updated, replaced, or rebuilt. Custom overrides are cleanly migrated to the new architecture.
5. SEO and redirect plan
Mapping legacy URLs, setting up individual 301 redirects, and checking tags, the sitemap and structured data before go-live.
6. Go-live and monitoring
The site is launched during off-peak hours, followed by real order tests and enhanced monitoring of traffic, errors and indexing for 30 days.
What we secure first
A failed migration impacts revenue within the first week.
Your existing SEO rankings
URLs are retained wherever possible, with 301 redirects set up when necessary. Page titles, meta tags and structured markup are preserved, then optimised.
Your sales history
Orders, invoices and credit notes remain accessible and compliant. Upgrading your PrestaShop version does not affect your accounting obligations.
Custom development
Custom overrides and modules are properly migrated to the PrestaShop 9.1 Symfony architecture—not patched together.
External integrations
ERP systems, marketplaces, shipping carriers, payment gateways and email marketing tools: every data flow is retested under real-world conditions before the switch.
The checkout process
Complete test orders using every shipping carrier and payment method, both before and after launch.
Performance
Migration is an opportunity to improve performance: caching, images, SQL queries and Core Web Vitals are all optimised.
Signs You Need to Migrate Now
- Your host has announced the end of support for your PHP version
- Your modules no longer receive security updates
- Your back office has become slow and unstable
- You can no longer add a feature without breaking something else
After the migration, keep your store healthy with PrestaShop maintenance or full store management. Our rates start at 90 €/hr.

PrestaShop Migration FAQs
Will I lose my SEO rankings when migrating to PrestaShop 8 or 9.1?
Not if the migration is properly planned. We preserve the existing URL structure, create 301 redirects for any URLs that change, retain title tags, meta descriptions and structured data, then monitor indexing in the weeks after launch.
Will my PrestaShop 1.6 or 1.7 modules work with PrestaShop 9.1?
Only some of them. The first step is a module-by-module compatibility audit to identify what is compatible, what needs to be repurchased and what requires custom redevelopment. You know the true cost before work begins.
Should you migrate to PrestaShop 9.1 now?
PrestaShop 9.1 is the latest major release, offering PHP 8.3 compatibility, an updated Symfony foundation, a faster back office, and ongoing security patches. If your store runs on version 1.6, 1.7, or 8 with modules that are still maintained, we audit compatibility and give you an honest recommendation: migrate to 9.1 now or secure your current version first.
How long will my store be offline?
Usually less than an hour. Everything is prepared and approved in a staging environment; the cutover is scheduled during off-peak hours, with the option to roll back at any time.
What happens to my customers, orders and invoices?
Everything is migrated: customers, addresses, orders, invoices, credit notes, products, variants, stock, pricing rules, and SEO data. A detailed data consistency check is carried out before and after migration.
