By default, WooCommerce does not support manufacturer (brand). Therefore, the manufacturers will be migrated to product attributes.
If you want to manage the manufacturers separately, you will need to install a Brand plugin to your WooCommerce store. Then, our technicians will customize your migration tool to migrate data to all Brand plugins at no extra cost.
We recommend using either of these brand plugins:
1. Brands for WooCommerce by BeRocket.
2. WooCommerce Brands by WooCommerce
