PrestaShop upgrade to version 8 and 9

A safe PrestaShop 1.7 upgrade to version 8 or 9: audit, migration on a copy, testing and a switchover without downtime.

What the upgrade includes.

A store on PrestaShop 1.7 works, until it doesn’t. An old version and old PHP mean no security patches, modules that stop working together and maintenance that gets harder every year. We upgrade the store to version 8 or 9 so it works as before, only more securely: without losing features, orders or Google rankings.

We explain the upgrade step by step, and what can go wrong, in our guide to PrestaShop 1.7 migration to 8 and 9. This page is about what we do for you. Planning a new store? See PrestaShop stores.

  • Migration audit: PHP, server, modules, overrides, theme and integrations
  • Migration on a copy of the store, with no impact on current sales
  • Updating or replacing modules, including custom ones
  • Adapting the theme to the new version
  • Switchover at night, with a full backup for a quick restore
  • Care after the upgrade in a maintenance package

The upgrade step by step.

  1. 01

    Migration audit

    We make a full copy of the store and a test environment. We check PHP, the database and the server, the modules (including custom ones and overrides), the theme and the integrations: payments, shipping, invoicing, marketplaces, mailing and analytics. You get a report with a decision for every module and a binding quote.

  2. 02

    Migration on a copy

    On a separate server we upgrade PHP and PrestaShop (version 8 or 9, depending on the audit), move products, customers, orders and content, update or replace modules and adapt the theme. The production store keeps running normally the whole time.

  3. 03

    Testing and acceptance

    We test the purchase flow, payments, shipping, invoicing, integrations and the admin panel. You get access to the test version and approve it before anything goes to production.

  4. 04

    Switchover and monitoring

    We deploy in an agreed window, usually at night when traffic is lowest, with a full backup of the database and files ready for a quick restore. Then we monitor the store and react quickly to any errors.

Why it is worth not waiting.

An old store doesn’t break overnight. Problems build up quietly until one day a payment method or a shipping integration stops working.

  • Security

    Older PrestaShop and PHP versions no longer get patches, so every new vulnerability stays open.

  • Modules and integrations

    Payment, shipping and module providers move on to new versions, and the old ones stop working with your store over time.

  • Server

    Hosting providers gradually retire old PHP versions. A store that needs them becomes hard to keep running.

How long it takes and what drives the cost.

We agree the dates and the quote after the migration audit, before we start.

Some paid modules from the older version need a new license or a replacement. We show these costs before work starts. If needed, we also move the store to a new server, ideally as a separate stage.

  • Usually 4-6 weeks

    From the audit to launch. It depends mostly on how many changes and new features you want along the way.

  • Modules

    Every module gets a decision in the audit: update, replacement or removal, together with its cost.

  • Theme and overrides

    Custom theme changes and code overrides are moved and adapted to the new version.

How long does a PrestaShop 1.7 to 8 or 9 upgrade take?
Usually 4-6 weeks from the audit to launch. It depends on the number of modules, integrations and new features you want along the way.
Will the store keep working during the upgrade?
Yes. We migrate on a separate copy, and the live store keeps running normally until the switchover, which we do at night when traffic is lowest.
Will I lose orders, customers or Google rankings?
No. We move products, customers, orders and content, and redirect changed addresses to keep your positions in Google.
Will my modules work after the upgrade?
Some will, some need an update or a replacement, and some paid modules need a new license. You get the decision for every module and its cost after the audit, before we start.
Version 8 or straight to 9?
It depends on the audit: on the modules, the theme and the server. We choose the version your store will run on reliably, not the highest number at any cost.
How much does a PrestaShop upgrade cost?
We quote after the migration audit, which ends with a report giving a decision for every module and a binding quote.
