Yes, you can!
As long as there are less than 30 days remaining in your current plan, you can directly upgrade to the "Group Plan" through the official website. The new plan will automatically stack after the old one and will not overlap.
Note: If you did not originally subscribe to the "Personal Plan" through the official website, please refer to this guide to cancel the original plan's renewal to avoid duplicate charges after the original plan expires.
