The Connector file is the best way to connect your shopping carts for starting migration. So for it, need to place the "mp_connector" folder in the root directory of the PrestaShop store.
How to use
Download the mp_connector file from your migration tool.
Then unzip it and upload the entire mp_connector folder into your PrestaShop store’s root folder using FileZilla Client or cPanel.
3. Access your_store_url/mp_connector/connector.php. You will get a “Connector successfully installed” message if it was uploaded successfully.
If you have any problems using the mp_connector, read how you can fix this issue or contact our support team.
*When you upload the mp_connector to your web server, you are giving our migration tool permission to access and read data from your store.
