I want to move from PrestaShop 1.7 to 9: what happens to my modules?

Many PrestaShop 1.6 and 1.7 themes and modules don't work on 9. Before switching, you need to know which ones fail and adapt or replace them.

With an agency or a freelancer

  • Upgrade services to PrestaShop 8 or 9 cost around €740 ($800), and tools €89 ($99) to €270 ($299).
  • The vendors themselves warn that old themes and modules are not compatible: adapting them is quoted separately.

With a general AI

  • It can adapt a module's code if you give it access to your files and an environment with PrestaShop 9 to test it.
  • Setting up that environment and testing the modules one by one takes technical knowledge, time and money.

With Devellia

  1. Devellia prepares a new PrestaShop 9 store for you and brings over your data.
  2. It checks your active modules for free and tells you which have a version for 9 and which would need adapting. Our team turns this check on for your store: ask for it with “Talk to a person”.
  3. Very soon, Devellia will also adapt the code of the modules that need it and test it on PrestaShop 9.

Adapting each module will cost what it uses, from €0.30 ($0.33), with a guaranteed cap you will see before starting: if it needs more, we will cover it.

Questions

Is anything published without me seeing it?

No. Devellia does it on a copy of your shop, you see it working and it's only published if you approve it. If you're not happy with something, it's undone.
