Hello!
My name is Anastasia, Ecwid Support. Thank you for contacting us! I will be glad to help you.
You can transfer the product catalog and customers from your existing store to Ecwid with the help of the Ecwid Import tool. We prepared a detailed instruction on how to migrate your store to Ecwid, please have a look:

If you need to transfer the products with options, you can use a special X-cart format. Please refer to this article for more details:

As for the indexed pages, it may be possible to create a redirect from the existing X-cart store product pages to the corresponding Ecwid product pages. So the already indexed pages will redirect the visitors to your new store. You can contact
X-cart Support to check how it can be accomplished.
I hope this will be helpful for you.
Please, let us know if you have any further questions.
