Yes you can. To do this you’ll need to login as your billing user and then visit the upgrade section on your account page. This works for any purchase. If you are upgrading from a single account type (Minecraft or Roblox) to our bundle and have purchased an annual subscription or lifetime membership, your previous purchase will be discounted from the upgrade price. Monthly subscriptions won’t be discounted against any upgrade. So if you’re thinking about signing up for one month before deciding on an annual or lifetime plan, you may want to consider our 30-day refund policy which comes with this option.
