Why Migrate Your PrestaShop Store?

A PrestaShop migration is one of the most critical technical decisions an online store owner can make. Whether you are upgrading to a newer version, switching hosting providers, or moving to an entirely new server environment, migrating your PrestaShop store requires careful planning and technical expertise.

There are several compelling reasons to undertake a PrestaShop migration:

Security updates: Older PrestaShop versions no longer receive security patches. Running an outdated version exposes your store and your customers' data to significant risk.
Performance improvements: Newer versions of PrestaShop offer considerably better loading times, optimized database queries, and more efficient resource utilization.
New features: Each major release introduces features that can boost your conversion rate and enhance the shopping experience for your customers.
PHP compatibility: Current PrestaShop versions support modern PHP versions that are not only faster but also more secure.
Hosting optimization: A server change can dramatically improve your store's speed, especially when moving from shared hosting to a dedicated server or cloud infrastructure.

Planning Your PrestaShop Migration

A successful PrestaShop migration starts well before the actual move. The planning phase is crucial and should begin at least two to four weeks before the scheduled migration date.

Conducting an Inventory

Before you start the migration, create a comprehensive inventory of your current store:

Module inventory: List all installed modules and verify which ones are compatible with your target version. Contact module developers if necessary to obtain compatibility information.
Theme analysis: Determine whether your current theme is compatible with the new PrestaShop version. Custom themes frequently require adjustments or complete rebuilds.
Document customizations: Have you modified core files or created override classes? These changes must be reimplemented in the new version.
Third-party integrations: Record all interfaces to external systems such as ERP software, inventory management, payment providers, and shipping carriers.

Creating a Timeline

Plan your migration during a low-revenue period. Avoid timeframes such as Black Friday, the holiday season, or other seasonal peaks. A detailed timeline with clearly defined milestones helps you maintain oversight and minimize your store's downtime.

Step-by-Step PrestaShop Migration Guide

The following guide walks you through the most important steps of a PrestaShop migration. Depending on your store's complexity, additional steps may be necessary.

1. Create a Complete Backup

The backup is the single most important step in the entire migration process. Without a complete backup, you risk losing all your data.

Database backup: Create a full MySQL dump of your PrestaShop database. Use mysqldump with the --single-transaction and --routines options to ensure a consistent backup.
File backup: Back up the entire PrestaShop directory including all subdirectories. The most critical directories are /img, /modules, /themes, /override, and /upload.
Configuration files: Store a separate copy of parameters.php or your .env file, as these contain your database credentials and store configuration.
Verify the backup: Test that your backup can be restored before proceeding with the migration. A backup that cannot be restored is worthless.

2. Install the Target PrestaShop Version

Install the target version of PrestaShop in a separate environment — ideally on a staging domain or test server.

Download the latest stable version of PrestaShop from the official website.
Set up a new database for the test installation.
Run through the installation wizard and note down the back-office credentials.
Ensure that the PHP version and server requirements match the new PrestaShop version's specifications.

3. Migrate the Database

The database migration is the most technically demanding part of the PrestaShop upgrade. Exercise particular care during this phase:

Schema comparison: Compare the database structure of your old installation with the new one. Tools such as mysqldiff or dedicated PrestaShop migration modules can assist here.
Data import: Import product data, customer information, orders, and CMS content into the new database. Pay attention to changed table structures and new required fields.
Character set verification: Ensure that the character encoding (UTF-8) is correctly transferred to prevent issues with special characters and diacritics.
Data integrity testing: After the import, spot-check products, categories, and customer accounts for completeness and accuracy.

4. Adapt Your Theme and Modules

After the database migration, you need to adapt your theme and modules for the new version:

Theme migration: If your theme is not compatible with the new version, you will need to either adapt it or switch to a new theme. When upgrading from PrestaShop 1.6 to 1.7 or higher, a completely new theme is typically required.
Update modules: Install compatible versions of all required modules. Test each module individually to identify conflicts.
Review overrides: Do not blindly transfer your existing override classes — verify whether the underlying core classes have changed.
Check hooks: Ensure that all modules are correctly registered to their respective hooks.

5. Testing and Quality Assurance

Before taking the migrated store live, comprehensive testing is essential:

Functional testing: Walk through the entire order process — from adding a product to the cart through to the order confirmation.
Payment testing: Test all payment methods in sandbox mode. Pay special attention to credit card payments, PayPal, and local payment methods.
SEO check: Verify that all URLs redirect correctly. Implement 301 redirects for changed URL structures to protect your rankings.
Performance testing: Measure the loading times of your most important pages and compare them with the values from your old installation.
Mobile testing: Test the store on various devices and browsers to ensure responsive rendering works correctly.
Email delivery: Verify that all automated emails (order confirmations, shipping notifications, etc.) are sent correctly.

Common Mistakes During PrestaShop Migration

Drawing from our extensive experience as a PrestaShop agency, we know the typical pitfalls that occur during migrations:

No backup or incomplete backup: The most common and most severe mistake. Always create a complete backup and test the restoration before making any changes.
Updating directly on the live server: Never perform a PrestaShop upgrade directly on your production system. Always use a staging environment for testing first.
Skipping version steps: For major version jumps (e.g., from 1.6 to 8.x), consider updating incrementally to minimize compatibility issues.
Ignoring SEO considerations: Without proper 301 redirects, you will lose valuable rankings and organic traffic. Create a comprehensive URL list before the migration.
Insufficient testing: Test not only the main features but also edge cases such as discount codes, tiered pricing, and special shipping rules.
Forgetting to clear caches: After the migration, all caches must be cleared — both the PrestaShop cache and server-side caches such as OPcache and Varnish.

PrestaShop Migration Costs

The costs of a PrestaShop migration vary significantly and depend on several factors:

Store size: The number of products, categories, and customers directly impacts the migration effort.
Version jump: An update within the same major version (e.g., 8.0 to 8.1) is considerably less expensive than a migration from 1.6 to 8.x.
Custom modifications: The more custom code and individual modules you have, the more complex the migration becomes.
Theme changes: If a new theme needs to be developed or adapted, this significantly increases the effort involved.
Third-party integrations: Interfaces to ERP systems, payment providers, and other external services must be individually reviewed and adjusted.

Generally speaking, migrations fall into three categories: simple migrations within a major version with minimal customizations, medium-complexity migrations involving a version change and several modules, and complex migrations with extensive custom development and numerous third-party integrations. In every case, request a tailored quote that is specific to your store's requirements.

When Should You Hire a Professional PrestaShop Agency?

Not every migration requires an agency. Simple updates within a minor version can often be handled by technically proficient store owners. However, there are situations where working with an experienced PrestaShop agency is strongly recommended:

Major version jumps: Migrating from PrestaShop 1.6 or 1.7 to PrestaShop 8 requires deep technical knowledge and experience with the differences between versions.
Custom modules: If you rely on bespoke modules that are essential to your business processes, the migration should be accompanied by experts.
High revenue: The more revenue your store generates, the higher the cost of unplanned downtime. A professional migration minimizes this risk.
Complex integrations: Stores with numerous interfaces to inventory management systems, marketplaces, and other platforms require specialized expertise.
Simultaneous relaunch: If you want to combine the migration with a design relaunch or category restructuring, an agency provides the necessary project management experience.
