PrestaShop Migration: 7 Stepsto Move Without Losing Traffic

PrestaShop migration: definition and key considerations for your store

A PrestaShop migration is the complete transfer of an online store—catalogue, orders, customers and configuration—to a new version of PrestaShop or a new server. This technical operation preserves your data while improving performance, security and PHP compatibility.

More than 300,000 stores worldwide run on PrestaShop (source: BuiltWith, 2026). Of those, 40% still use a version earlier than 8.x, leaving them exposed to unpatched security vulnerabilities and without support for PHP 8.2+. Migration is no longer a luxury: it is a technical necessity for keeping your store operational and visible in Google.

The real difficulty of an ecommerce redesign centres on three areas: module compatibility, preservation of search visibility and continuity of orders. A single missing 301 redirect can wipe out months of SEO work. This guide explains every stage of moving your PrestaShop store without losing data or traffic.

Why migrate your PrestaShop store in 2026?

PrestaShop 1.6 has received no security patches since 2019. PrestaShop 1.7, although newer, has reached its official end of life. Versions 8.x introduce a redesigned Symfony 6 administration interface, 25–40% faster server performance on catalogue queries (source: PrestaShop, 2025) and native support for PHP 8.1 and 8.2.

Beyond security, migration addresses direct business concerns. Reducing loading time by one second increases conversion rates by 7% on average (source: Deloitte, 2023). Stores running PrestaShop 8 have an average Core Web Vitals score 30 points higher than those on version 1.7, directly affecting Google rankings (source: Google, 2024).

Module compatibility can also prompt a move. Developers are gradually ending support for versions 1.6 and 1.7. Remaining on an obsolete version means locking your business into a shrinking ecosystem. If your store relies on essential PrestaShop modules, check their 8.x compatibility now.

Three PrestaShop migration approaches compared

The right migration method depends on three variables: the size of your catalogue, the number of customisations and your budget. An automated module suits small, standard stores. A developer-led manual migration handles intermediate cases. A specialist agency manages complex projects involving ERP integrations, bespoke modules and large catalogues.

Each approach involves different trade-offs between cost, time and risk. Automated modules are quick but cannot handle custom overrides. Manual migration offers more control but calls for deep technical expertise. An agency provides the assurance of a tried-and-tested process, at a price proportionate to the workload. The table below summarises the main differences to help you decide.

Protecting SEO during migration

72% of ecommerce website migrations lead to a fall in organic traffic within the following three months (source: Ahrefs, 2024). The main cause is missing or incorrectly configured 301 redirects. Google takes between two and 12 weeks to recrawl and reindex a migrated website; during this period, each 404 error erodes domain authority.

The SEO strategy begins before migration. Export all indexed URLs from the Pages report in Search Console. Create a comprehensive mapping file connecting old and new URLs. If your URL structure changes during an SEO redesign, double-check everything: every product, category and CMS page needs a corresponding redirect.

Immediately after the switch, submit the new sitemap.xml in Search Console. Monitor the Coverage report daily for four weeks. Correct 404 errors within 24 hours. Set up automated alerts for high-traffic pages to detect any abnormal fall in clicks or impressions. At the same time, confirm that your basic PrestaShop SEO settings are active on the new version, including friendly URLs, meta tags and server caching.

Tangible results from two SME migrations

A fashion retailer with eight employees and 3,200 products migrated from PrestaShop 1.6 to 8.1 in six weeks. Loading time fell from 4.8 to 1.9 seconds. Its conversion rate rose from 1.2% to 2.1%, a 75% increase. Organic traffic returned to its original level within three weeks thanks to complete redirect mapping for 4,800 URLs.

An organic-products distributor with 12 employees and 8,500 SKUs changed servers while moving from PrestaShop 1.7.8 to 8.2. Its total budget was €9,500, including the audit, migration and three months of post-migration support. The outcome was a 55% reduction in server time, 32% more organic traffic after 90 days and no lost orders during the switch. The key was a staging environment tested for two full weeks before launch.

Both examples show a consistent pattern: PrestaShop migration produces measurable ROI when it follows a structured process. If you operate a PrestaShop website with more than 1,000 products, the investment can pay for itself within three to six months through improved conversion and lower server costs.
