How can I upgrade my membership?
If you are going to upgrade your membership from a lower one to a higher one, such as from a basic plan to a professional plan, you don’t have to request a cancellation of your current membership or a refund.
Directly purchase the higher membership that you want to upgrade to, the duration of your current membership will be automatically combined into the new one with a certain conversion rate, which is an equal-value conversion based on the price of each membership.
