I have used them twice - the first migration was for a client whose site was on Magento Go, which was shut down - Cart2Cart migrated my client's website perfectly. More recently, they have migrated a website from an ancient version of Cubecart to WooCommerce. The migration service is absolutely incredible and just works perfectly but the best bit is their support staff - they help the whole way and are polite and very responsive. A truly excellent company that I would recommmend wholeheartedly! Thanks.
