Basic Migration Service is a service helping you to migrate products, customers, orders, categories and other data from one shopping cart to another. The process can be performed at https://cm.litextension.com. After purchasing migration service, you will set up a cart and other required steps to run full migration on your own, with a clear migration guide provided.
We at LitExtension always available to help you when you need. Please feel free contact us if you have any question.
