Cart2Cart Store Migration App

We migrated a large x-cart site to shopify. This was the only app that could help us migrate hundreds of thousands of orders and customers. They were extremely knowledgeable and responsive. They answered my questions quickly and accurately. The initial migration went smoothly with no errors. The final migration at launch (to bring in the newest orders and customers) went equally as well. Data security was also handled to my satisfaction. Definitely would recommend this app.
