What URL address should I use for Migration Wizard?
On the Migration Wizard you will be asked to paste your store URL. It has to be your front end URL, but not admin panel URL.
Please note, Big Cartel is a hosted shopping cart that allows merchants to change the initial domain name of your store to a unique one. However, in order to perform an automated data migration, you have to use the default URL address. It has to look like www.your-source-store.bigcartel.com as the only required data for your Big Cartel store.
