Hello.
What you want to do is complicated, joining two databases from two different CMS is not an easy task
You can try the following WP plugin ->
What this plugin does is check the WP and prestashop records so that they can be accessed on both platforms, what you will not care about will be the users that you have already created in PS.
You can export all PS users to import them later in WP.
.- Modules -> Modules and edit Export customers
This will create a csv file with the user data to be able to import them into WP.
.- install the following plugin in WP ->
What this plugin does is that you can import the users through a CSV file that is the one you created previously.
To use it, you will find the “Members Import” option in the users menu.
You can even tell it to send each user their password by email.
A greeting.
