Keeping Selling Point After Your Successful Migration

Selling Point is built to be merchant first. So once you are done migrating your Gift Cards you don't have to keep the application. From that point onward you'll be using Shopify's backend to manage Gift Cards. Once you uninstall the app all of your migrated Gift Cards will continue to function natively on Shopify. However, if you have more migrations to do in the future feel free to keep the app!
