Upgrade From Prestashop 1.6 to the latest version compatible with Modules

Upgrade From Prestashop 1.6 to the latest version compatible with Modules, please note that I have a lot of products and that would be the issue, but I think it won´t be difficult to upgrade.

I am looking for a skilled developer to upgrade my current Prestashop 1.6 website to the latest version that is compatible with modules (Just a few modules)

Current Version: Prestashop 1.6.1.24

I don´t have a backup but I have the products information including image URLs

Specific Modules/Functionalities: I want to ensure that all my existing modules and functionalities remain compatible after the upgrade.

Ideal Skills and Experience:
- Strong experience with Prestashop development and upgrades
- Knowledge of the latest version of Prestashop and its compatibility with modules
- Ability to handle data migration and backups
- Attention to detail to ensure all modules and functionalities are properly upgraded and compatible

Please provide a detailed proposal outlining your approach to this upgrade project and any relevant experience you have.
