If PrestaShop and WordPress are not installed on the same host, you can do this:
– export the PrestaShop database to a SQL file (with phpMyAdmin for example)
– import this SQL file on the same database as WordPress
– run the migration by using the WordPress database credentials (host, user, password, database) instead of the PrestaShop ones in the plugin settings. You can find the WordPress credentials in the wp-config.php file.

The documentation about doing a migration in local can be found here (for Windows): https://www.fredericgilles.net/migrate-wordpress-local-windows-server/ (or for Mac): https://www.fredericgilles.net/how-to-migrate-to-wordpress-from-various-cms-on-a-mac-local-server/
