before making updates on Prestashop, it is recommended to make backups of our website. To do this you can follow this guide.
To update Prestashop 1.7, we have a module developed by the Prestashop team called 1-Click Upgrade. We can install it as indicated in this guide by searching for its name: 1-Click upgrade
After installing the module, an option called More > 1-Click Upgrade will appear in the menu. If we access this, we will open the module to manage the update.
To search for updates, we must click on the Check if a new version is available button, located at the bottom in the Start Update section.
In case there are pending updates, it will indicate that there is a new version to install. Click on Update and it will start updating Prestashop.
