Please note that you don't need to click on your domain name, just the Active button as on the screenshot.
Choose Upgrade/Downgrade action.
Select the preferred hosting plan and press Choose Product.
Upgrade price is calculated from a credit of the unused portion of the current plan and billing of the new plan for the same period.
Your hosting plan will be upgraded as soon as the payment is processed.
