How to transfer theme license from one store to the other
If you are intending to close the store that your current theme license is activated, you should transfer the theme license to the new store.
Theme purchased from Shopify Theme store
If you purchased your theme from Shopify directly, you need to contact their support team to have the theme license transferred to the new store. It involves permanently shutting down your current store first and then transferring the license to your new store.
They will help you facilitate the whole process. Note that we verify proper licensing of themes while providing support, so you must have your theme license properly activated on your store before we can provide support or you can download the latest version of your theme.
