The Connector Bridge file is the best way to connect your shopping carts for starting migration. In order to accoplish it, the "mp_connector" folder should be uploaded to the root directory of the PrestaShop store.
Fill the Source Store URL field and download the "Connector Bridge file" file from the migration dashboard
Then unzip it and upload the entire mp_connector folder into your PrestaShop store’s root folder using FileZilla Client or cPanel.
If you have any problems using the mp_connector, read how you can fix this issue or contact our support team.
Skip this step if the migration is created using the Shopify App, because the Target Store connects automatically.
Alternatively (if migration is created from the MigrationPro SaaS),
fill in the Target Store URL and API Password fields.
Next step: Click "Next: Configure your migration" to proceed.
*When the mp_connector is upload to your web server, the migration tool gains permission to access and read data from your store.
