IMPORTANT UPDATE: AutomateWoo has moved to the WooCommerce Extensions Store which means product licenses are now managed on WooCommerce.com. If you need help with your WooCommerce.com subscription please refer to the guide on Managing WooCommerce.com subscriptions.
AutomateWoo subscription purchased on WooCommerce.com can be upgraded. At the checkout page you will be asked to pay the difference between subscriptions. To upgrade your your extension please see Upgrading Keys and Subscriptions.
Legacy AutomateWoo.com subscriptions can no longer be upgraded.
