Since iStore WooCommerce theme provides extensive options and a robust option panel to manage your website with, it also provides a backup theme options system. This is useful in case you want to move your website to another host or if you are setting up the theme from scratch and want to retain the existing settings of your theme options.

You can download the existing theme data by clicking the Download Data File button. This will generate a .json file and download on your hard drive. You can then import the same file using this same Import/Export screen.

Click the Import From File button, and select the .json file. It will import all your theme options in the new site.
