Changing the Billing Mode from Yearly/Monthly to Pay-per-Use

Scenarios

You can change the billing mode of a DB instance from yearly/monthly to pay-per-use.

You can change the billing mode from yearly/monthly to pay-per-use either immediately or upon expiration.

• Immediately: Once the change order is complete, the remaining fees for the current subscription terms are refunded, and pay-per-use billing takes effect immediately.
• Upon expiration: The pay-per-use billing mode takes effect only after the yearly/monthly subscription has expired.
