Why do you need to upgrade PrestaShop?

Upgrade or not to upgrade – it is up to you – but the latest versions always bring lots of new ecommerce opportunities that can pass you by if you choose to stick to the dated PrestaShop release. Do not let the competitors take a huge step forward before you do – let’s check out the benefits that you gain using an updated PrestaShop platform.


Security is where it all begins and hopefully does not end. Running an online store, you need to be sure that both customer data and your own are safe – it should become your prime consideration. PrestaShop updates contain fixes that eliminate security vulnerabilities so they should be applied regularly as soon as a new release comes out.

Technologies are developing and hacker approaches become smarter and more sophisticated. If you keep your online store on the same level and ignore innovations, it can still be damaged by the same kind of hacker attack that your competitors have forgotten about a long time ago. One more day without upgrades – one more good chance for the hackers to get in.

For example, developing the version, the PrestaShop team had managed over 7,300 files and fixed 249 bugs that were observed in 1.7.5x versions. It resulted in this ecommerce platform becoming a more mature and reliable solution that gains the trust of both small businesses and large brands.


Timely upgrades do not only secure your online store but also help to maintain the website’s stability. Do not lose your customers due to the issues of an outdated platform and low performance. If it takes too much time to load the page, there is a high chance that most of them will leave directly. In order to avoid it, upgrade your PrestaShop and keep the shopping experience of your customers smooth and efficient.

For example, the users that have already upgraded PrestaShop to the version noticed that fixed bugs and speeded up performance made the platform much friendlier to both backend users and customers.

How to Upgrade PrestaShop with 1-click Upgrade Module

If you find the manual upgrade process too tedious, there is an alternative – a free PrestaShop 1 click update module. But before upgrading PrestaShop by this method, you need to:

1) Install the latest version of the module.
2) Make sure that your server has enough resources as the 1-click module is quite resource-intensive. If your server is weak, the module might not run.

If everything is alright, you can start upgrading PrestaShop via 1-click module following these steps:

Step #1: Follow the link to download the 1-click upgrade module from the PrestaShop marketplace.

Step #2: Install the module this way: go to Improve tab -> Modules -> Module manager and click the Upload the module button in the upper right corner. Choose the 1-click upgrade module zip from the folder tree.

Step #3: The installed module will welcome you with the Preupgrade Checklist; before you proceed to the upgrade, make sure that every point here has a green tick.

Wrapping it up

In the article, we have described two ways to upgrade your PrestaShop-based online store to the new version. It is up to you which one to choose. The manual method allows you to be fully in charge of the upgrade process and make certain changes to the system on the way if needed. While upgrading through a 1-click module requires less time, effort and development skills. We recommend this method to those who do not possess advanced developer skills and want to upgrade PrestaShop without any modifications.

  1. Works great on all PS 1.7 versions. However:

    if you made any modifications to your email standard messages of your standard pdf invoices, please delete both the folders MAILS and PDF from your new installation. This prevents the new Prestashop version overriding all of your modifications.

  2. Well described! I have an online store on PrestaShop and recently I wanted to upgrade the latest version of PrestaShop and searched a lot for a detailed step by step guide for the upgrading process but couldn’t find something special. Now I have got what I want. Thanks for the article.

  3. Thank you for the comment and feedback, Rene! You are right, there is still quite some information that we can add to this article to improve it. We are going to update it in the future, describing PrestaShop upgrade more in-depth. Stay tuned with our blog!

  4. Update steps are great! It works easily if you follow the steps.
    However: if your site uses an other theme than the standard, your .css files are messed up. Also, some module posititons may be different after the upgrade.
    Lastly, the mail templates and pdf templates may be set back to standard after the upgrade.
