Hi @Charlieim !
@Ihor-Sh is correct, Matrixify is able to migrate from WooCommerce using the WooCommerce API. It is worth a try to see if the Matrixify app fits your needs in this case. We offer a free demo plan you can use for an unlimited amount of time for an unlimited amount of Imports/Exports. The only catch is that you will only be able to Import/Export 10 items at a time, however, it is a fantastic way to get a feel for the app and test it out. It will work great for testing out if the Matrixify app is able to migrate the data for you.
You can also reach out to our support and we can look into this for you in a little more detail.
