PrestaShop 8 / 9

PrestaShop version 9 introduces significant changes and advancements in architecture, technology, and user experience. Below, we compare its advantages against the older and widely used 1.7.x version.

---

Why Upgrade from Older Versions?

Before exploring what version 9 brings, it is important to understand why moving away from an older release such as 1.7—or even PrestaShop 8+—is essential:

1. Security and Updates

   Newer versions continuously receive security patches, bug fixes, and core issue resolutions that help protect your e-commerce store from vulnerabilities and attacks. A store running on an older version, especially 1.7, may remain exposed to known security issues that are already addressed in newer releases.

2. Compatibility with Modern Technologies

   New PHP versions, frameworks, libraries, and requirements from external systems (such as APIs, services, and payment gateways) are often not supported by older versions. Modern PrestaShop releases target PHP 8.1–8.4 and Symfony 6.4, ensuring improved compatibility and long-term support.

3. Performance and Speed

   With major architectural improvements in the open-source core, upgraded caching mechanisms, and the adoption of modern technologies, newer versions deliver:

   a. better performance,
   b. faster page loading times, and
   c. a smoother user experience
   
   
4. Users tend to abandon slow pages—therefore, speed has a direct impact on sales and conversions.
5. SEO and User Experience (UX) Improvements

   Modern releases provide enhanced SEO capabilities, including cleaner URLs, structured data, improved redirect management, and support for image formats such as WebP and AVIF. Significant improvements have also been made in website administration, with a more refined User Interface (UI), better ergonomics, and simplified forms for managing products and categories.

What’s New in PrestaShop 9

Let’s review the key innovations and improvements introduced in version 9 compared to versions 1.7 and 8+:

1. New Technology Stack: Symfony 6.4 & PHP 8.1–8.4
   The platform now runs on a more modern and fully supported framework (Symfony 6.4) and supports the latest PHP versions (8.1 to 8.4).
   This ensures easier maintenance, higher security, and better compatibility with modern libraries.

2. New Admin API
   Version 9 introduces a new management API (Admin API), based on API Platform, allowing back-office functionalities to be exposed through REST/JSON and enabling easier integrations with external systems such as ERP and CRM solutions.
   This paves the way for more flexible extensions, integrations, and automation workflows.

3. New Default Theme — Hummingbird
   The new default theme, “Hummingbird,” is mobile-first, built on Bootstrap 5, and features a cleaner, more modern design.
   This helps your store start with a stronger visual foundation and improved performance.

4. SEO, URL & Redirect Management Enhancements
   The new version offers more flexible URL control, improved redirect management (301 / 302), support for WebP/AVIF image formats, and a cleaner SEO structure.
   This can significantly improve search engine rankings.

5. Update Assistant Tool
   The upgrade process becomes safer and smoother through the new Update Assistant, which guides each upgrade step and helps manage modules and themes efficiently.

6. Codebase Cleanup and Reorganization
   Extensive work has been done to modernize the technical foundation, reducing legacy code, improving separation of concerns, dependency control, and adopting more modern design patterns.
   This makes the platform far more flexible for future expansions and customizations.

7. Improved Back Office User Experience
   The administration experience has been refreshed with a cleaner interface, more ergonomic structure, and better accessibility.

Comparison: Version 9 vs 1.7 — Benefits and Challenges

Area	Advantage of Version 9 over 1.7	Upgrade Challenges
Security / Maintenance	Continuous support, fixes, and compatibility with new libraries	Every module/theme must be checked for compatibility
Technology	Symfony 6.4, PHP 8.1–8.4, modern architecture	Possible incompatibilities in legacy code
Scalability / API	New Admin API for easier integrations	Requires validation of the endpoints currently used by your store
Interface / UX	New theme and improved back-office experience	The existing theme may require adjustments
SEO & Performance	Enhanced SEO features, WebP/AVIF support, faster loading times	New capabilities must be configured properly to maximize results
Cost / Effort	Long-term benefits and reduced technical debt	The process requires careful execution, testing, and possible refactoring

If the upgrade is carried out correctly—with a staging environment, compatibility checks, and a phased rollout—major structural disruptions can be avoided.

Upgrade from 1.7 Without Major Structural Changes

An important advantage worth highlighting is that migrating from 1.7 to 9 can often be completed without requiring a full redesign of the theme or replacement of all modules, provided they are well-built and supported for compatibility.

• Many 1.7 themes and modules already follow standards that facilitate upgrades—several can continue working with minor adjustments and without radical changes.

• The new Update Assistant helps automatically identify incompatibilities and provides practical guidance.

• Front-end customizations (CSS, templates) can often be preserved as much as possible through gradual modifications instead of a full redesign.

• The process should always follow staged steps: first on a staging environment, then functionality validation, and finally deployment to live production.

This way, the client experiences minimal disruption while preserving the store’s original identity with as few changes as possible.

Our Company’s Expertise

Our company specializes specifically in PrestaShop upgrades from older versions (such as 1.6 and 1.7) to modern releases like version 9, with a strong emphasis on avoiding “mass migration” automations or plug-and-play modules that claim to handle everything automatically.

We offer:

• Handcrafted methodology: every upgrade is carried out through detailed analysis, phased execution, and controlled interventions to ensure the existing store functionality remains intact.

• Module and theme compatibility auditing: we proactively identify which extensions require adaptation or replacement and build a smooth migration strategy.

• Preservation of your existing design as much as possible, with targeted adjustments only where necessary.

• Money-back guarantee: if the upgrade fails or does not meet the agreed specifications, we offer a refund of the project cost (according to pre-agreed terms).

This approach gives the client a guaranteed outcome with minimal risk and without the need for radical store reconstruction.

Is It Worth Upgrading Now?

The migration from PrestaShop 1.7 or 8 to version 9 is essentially a leap toward a more modern, secure, and scalable platform. The benefits in security, performance, SEO, and future extensibility are substantial. Despite potential challenges (such as theme or module incompatibilities), the process can be executed carefully, gradually, and with minimal disruption.

Our company has the expertise to deliver this transition through a handcrafted approach, ensuring the smooth operation of your store and protecting your investment with a service guarantee.
