An online store is constantly evolving. The product catalog grows, new integrations are added, business needs change, and customers expect an increasingly fast and seamless experience.
The technology platform must also keep pace with that evolution.
Updating PrestaShop isn't just about changing a version number. It's an opportunity to review the store's architecture, modernize the technical environment, and build a more stable, compatible, and maintainable foundation.
At TRILOGI, a PrestaShop Three-Star Expert, we approach these projects from a comprehensive perspective: platform, modules, theme, customizations, integrations, infrastructure, and business operations.
What does it mean to update a PrestaShop store?
Updating PrestaShop means upgrading a store to the most recent maintenance release within its current branch. For example, upgrading from an older version of PrestaShop 8.2 to the latest version available in that branch.
A migration usually involves a more far-reaching change, such as upgrading from PrestaShop 1.6 or 1.7 to a current version of the platform. In these cases, simply updating the core is not enough: you must also assess the compatibility of modules, themes, custom developments, overrides, connectors, and the server environment.
The official PrestaShop documentation explains that PrestaShop follows a model based on major, minor, and maintenance releases. Maintenance releases allow for the inclusion of fixes and improvements without introducing significant functional changes.
Why is it a good idea to keep PrestaShop up to date?
1. A more stable technological foundation
Maintenance releases include improvements designed to enhance the platform's performance.
PrestaShop recommends using the latest versions to take advantage of the stability fixes included by the project. Before updating, it also advises making a complete backup of the files and the database.
Regular maintenance allows for gradual improvement through smaller, more controlled interventions, rather than letting a large technological gap develop.
2. Greater compatibility with the ecosystem
A PrestaShop store consists of several layers:
- The core of the platform.
- The modules.
- The topic.
- Custom developments.
- Overrides.
- Integrations with external systems.
- PHP, the database, and the server.
For this reason, a well-planned update should take the entire system into account and not be limited to the core. The technical document provided for this content also highlights the importance of taking stock of modules, themes, customizations, integrations, and the environment before defining the update strategy.
This review helps identify which components can be updated directly, which ones need to be adapted, and which ones should be replaced with more up-to-date alternatives.
3. A modern server environment
Compatibility between PrestaShop, PHP, the web server, and the database directly affects the maintainability of a store.
For PrestaShop 8, the official documentation recommends PHP 8.1, Apache 2.4 or later, and recent versions of MySQL or MariaDB. It also recommends having at least 256 MB of memory per PHP process.
Working in a modern environment makes maintenance easier, allows you to take advantage of language improvements, and promotes compatibility with current tools.
4. Updated and better-integrated modules
Modules expand PrestaShop's capabilities: payment methods, filters, logistics, marketing, analytics, search engines, and integration with business systems.
Keeping them up to date allows you to incorporate the improvements released by their developers. A recent example is the official faceted search module, ps_facetedsearch, version 4.0.4 of which was included in the PrestaShop 8.2.7 and 9.1.4 distributions.
This model demonstrates one of the advantages of the PrestaShop ecosystem: the project can release updated versions of its components and make it easier for stores to incorporate those improvements through a planned process.
5. Greater ability to evolve
An up-to-date database makes it easier to add new projects:
- User Experience Redesigns.
- New payment solutions.
- Integrations with ERP, CRM, or PIM systems.
- Logistics automation.
- Internationalization.
- Business Customization.
- Performance improvements.
- Advanced analytics.
- Omnichannel strategies.
When the architecture is well-organized and documented, the team can devote more effort to creating value for the business and less to maintaining legacy compatibility.
When is it best to update, and when is it better to migrate?
The answer depends on the current version, the store's architecture, and its objectives.
Stores Using PrestaShop 1.6
PrestaShop 1.6 belongs to an older generation of technology. For these projects, it is usually advisable to plan for a complete and controlled migration.
Upgrading to a current version also helps strengthen the store’s security by running on a platform that receives maintenance updates and is compatible with newer versions of PHP, modules, and server components. This helps reduce the vulnerabilities associated with outdated technologies and facilitates proactive e-commerce management.
The analysis must include:
- Data quality and structure.
- Installed modules.
- Custom-developed features.
- Theme and user experience.
- External integrations.
- Trade Rules.
- Infrastructure.
- Future business needs.
Rather than simply replicating the existing store, a migration can be used as an opportunity to streamline processes, remove components that no longer add value, and design a solution that is ready for the years ahead.
Stores Using PrestaShop 1.7
In PrestaShop 1.7, the approach will depend on the subversion, the modules, and the level of customization.
From a security standpoint, upgrading to the latest version reduces reliance on outdated libraries, modules, and technology stacks. It also makes it easier to apply new patches and ensures coordinated maintenance of the core, the server, and installed extensions.
Upgrading to the current version allows us to modernize the technical foundation and align it with the development model adopted by the project starting with PrestaShop 8.
In these cases, it is especially important to perform a compatibility audit before deciding on the migration destination.
Stores Using PrestaShop 8
PrestaShop 8 remains a viable platform for many online stores as long as it is kept up to date with the latest version of its branch and its components are properly maintained.
Currently, the PrestaShop 8 documentation itself notes that a newer version is available and directs developers to the PrestaShop 9 documentation.
This does not mean that all businesses must make the switch immediately. The decision should take the following into account:
- Module compatibility.
- Theme and Customizations.
- Critical integrations.
- Business Calendar.
- Project cost.
- Technical and functional benefits.
- E-commerce Roadmap.
For some stores, it will be best to first upgrade to the latest version of PrestaShop 8.2. For others, especially when facing a redesign or a major update, it will make sense to consider migrating directly to PrestaShop 9.
How do you perform a PrestaShop migration?
Whether you're wondering how to migrate to PrestaShop 9 or the new 9.2 version, a professional migration should be structured in several phases.
1. Technical and Functional Audit
The first phase involves accurately identifying the starting point:
- PrestaShop version.
- PHP and database versions.
- Catalog and order volume.
- Active modules.
- Overrides and core modifications.
- Topic.
- Integrations.
- Back-office processes.
- Performance.
- Future needs.
The goal is to build a reliable inventory and identify dependencies before taking action.
2. Defining the Target Architecture
With the audit complete, the following decision is made:
- Target version.
- Infrastructure.
- Modules to be retained.
- Components to be replaced.
- Necessary adjustments.
- Data Migration Strategy.
- Testing Plan.
- Production Launch Plan.
Not all stores need the same solution. A B2C e-commerce site with a small product catalog presents different challenges than an international operation connected to an ERP system, multiple warehouses, and multiple sales channels.
3. Setting Up a Standalone Environment
The migration must take place in an environment separate from the production store.
This allows you to configure the new platform, customize modules, import data, and run tests without disrupting day-to-day business operations.
4. Data Migration and Validation
Among other things, the following must be validated:
- Products and Combinations.
- Categories.
- Clients and addresses.
- Orders.
- Taxes.
- Transportation Rates.
- Images.
- Discounts.
- Contents.
- URLs and redirects.
- Multi-store or multilingual configurations.
The migration must preserve business consistency; it should not be limited to simply copying tables between databases.
5. Functional Tests
Before launching the new store, the main navigation paths should be tested:
- Navigation and Search.
- Filters.
- Registration and Login.
- Shopping Cart.
- Special Offers.
- Checkout.
- Payments.
- Carriers.
- Transactional emails.
- Order Management.
- Billing.
- Integrations.
- Mobile display.
It is also a good idea to include performance, indexing, and analytics tests.
6. Deployment and Monitoring
The final migration must be planned to minimize service disruption and prevent the loss of data generated during the transition.
After launch, logs, orders, payments, integrations, performance metrics, and indexing are reviewed to confirm that everything is working as expected.
What to Check Before Updating PrestaShop
Before starting the project, we recommend answering these questions:
- What exact version of PrestaShop does the store use?
- Which modules are really necessary?
- Which ones are up to date and supported?
- Are there any direct changes to the core?
- Are there any overrides or custom developments?
- Is the theme compatible with the target version?
- Which external systems exchange information with the store?
- Are there verified copies of the files and database?
- Is there a representative test environment?
- How will the checkout and critical processes be tested?
PrestaShop recommends creating a full backup before using its update tool. Furthermore, the backup must be restorable: it is not enough for the automated process to indicate that it was created successfully.
Technical Updates and SEO: They Must Go Hand in Hand
An e-commerce migration can also affect organic search rankings. To protect your existing visibility, you must either keep or properly redirect:
- Category and product URLs.
- Meta titles and meta descriptions.
- Canonical tags.
- Headings.
- Structured data.
- Editorial content.
- Sitemap.
- Robots and indexing rules.
- Internal link.
- Manufacturer and brand pages.
- Pagination and filters.
PrestaShop templates allow you to manage elements such as the title, meta description, robot instructions, and canonical URL within the header of each page.
Therefore, the migration plan should include a before-and-after SEO comparison, along with a redirect map and indexing tracking.

Upgrading or Migrating PrestaShop: A Strategic Decision for Your E-Commerce Business
Updating PrestaShop allows technology to keep pace with e-commerce.
Stores based on PrestaShop 1.6 or 1.7 can take advantage of the migration to modernize their architecture, strengthen security, review processes, and reduce their reliance on legacy components. In PrestaShop 8, keeping the branch and modules up to date provides a solid foundation while you assess the right time to upgrade to PrestaShop 9.
The key is planning: audit first, define a coherent architecture, work in a test environment, and validate each critical process before deployment.
With the right strategy, migration ceases to be a purely technical endeavor and becomes an opportunity to drive e-commerce growth.
