PrestaShop update: How can you update your store safely?

Start with the installed version, specific problems, security notices and extension requirements. We would first establish which target version suits the existing store. The highest version number is not a sufficient reason on its own. The theme, modules, custom code and server environment need to work together.

A minor version change and a move across several major versions therefore require different scopes of work. For a store that has not been maintained for some time, preparation may take more effort than the update itself. That is not automatically a reason to leave PrestaShop. Existing processes and customisations may have considerable value that an update can preserve.

If you also want to redesign the catalogue, navigation, ERP and storefront, the project goes beyond maintenance. Our article on PrestaShop migration covers that different task. This article focuses on controlled development of an existing installation.

The official Update Assistant, formerly “1-Click Upgrade”, supports updates, backups and restoration. PrestaShop provides both a back-office interface and command-line use, as explained in its module overview.

A tool cannot know every commercial detail of your store. It can support a technical process; a suitable test must establish whether your custom B2B discount still calculates correctly afterwards. A completed update does not automatically confirm that every extension works.

Before using the tool, we would record the intended version and update route for the particular starting point. Where module providers are involved, their compatibility confirmation belongs in the preparation. Missing compatibility information is an unresolved task, not implied approval.

Merchants and the technical team need a shared basis for approval:

• Starting point: document the store version, server environment, theme, modules and custom changes.
• Target version: establish technical requirements and compatibility of business-critical extensions.
• Backup: back up files and database together, and practise restoration in an appropriate environment.
• Test store: restrict access, keep search engines out and prevent real payments, customer emails and production ERP orders.
• Acceptance: agree specific order scenarios and the people responsible for testing them.
• Maintenance window: coordinate timing, data reconciliation, rollback and availability of the people involved.

A backup on the same server is not a complete recovery plan. What matters is who can restore it, which data it contains and how long recovery takes. Working access credentials are part of that preparation.

We would derive a manageable set of meaningful tests from your daily business. This includes a normal order and the cases that actually generate your sales: variants, quantity discounts, customer groups or different destination countries. A simple test product will not cover a complex B2B store.

Consider a hypothetical specialist retailer selling individual items and full cartons. After the update, product pages look correct, but a customised quantity rule could calculate the wrong cart price. The relevant test therefore checks quantity, price, tax, shipping and the transferred order line together. This is a testing example, not a claimed customer case study.

Where there is an ERP connection to PrestaShop, we would also follow order transfer, status feedback and stock changes. A successful checkout does not tell us whether the warehouse received the correct order. These tests should use controlled records without unintended processing in production systems.

New orders, customer records and stock movements occur while the test copy and live store run separately. The tested copy must not simply replace the production database. The update appointment needs an agreed way of handling these changes and the connected systems.

Restoring a backup does not turn back time in every system involved. If a payment provider has accepted a payment or the ERP has processed an order, restoring the store database will not undo those actions. Agreed stop criteria and reconciliation of affected transactions help avoid conflicting records.

We recommend a defined maintenance window with a clear release decision. Promising no interruption at all without knowing your installation would not be credible. A rehearsal provides a much better basis for estimating the window than a generic number of hours.

A comparable quotation separates the initial assessment, test environment, adaptations, acceptance testing and follow-up checks. It also explains dependencies on third parties and what happens if a module is incompatible. A low fixed price is of little use if recovery or ERP testing is missing from the scope.

As a PrestaShop agency, we can consider technical maintenance and ongoing development together. We see PrestaShop as a particularly useful foundation for merchants who need their own processes and are prepared to maintain them. An update should protect that investment. Whether it also improves speed is a separate question, covered in slow PrestaShop stores.

For an initial discussion, bring the store version, an overview of important modules and a description of indispensable order processes. These let us define an assessment: what can be retained, where adaptation is required and under which conditions the update can be approved.
