Hi Judy,

This is Andrew from Ecwid Team. Thank you for your question.

Yes, it is possible to import customers via CSV file please read more: Importing customers – Ecwid Help Center

As for the order I am afraid it is not possible as Ecwid and X-cart are different shopping carts and the order placed in X-cart store will remain in X-cart store.

Please let me know if you have any questions.
