This topic describes how to change the billing method of an ApsaraDB for MongoDB instance from pay-as-you-go to subscription. Changes to the billing method do not impact on the running of the instance.
Prerequisites
- The instance is in the running state.
- The billing method of the instance is pay-as-you-go.
- The instance has no unpaid subscription orders.
- The instance type is available for purchase. For more information about unavailable instance types, see Historical instance types. If you want to change the billing method of an instance whose instance type is unavailable now to subscription, change the instance type first. For more information, see Configuration change overview.
Precautions
- The billing method of a subscription instance cannot be changed to pay-as-you-go. Exercise caution when changing the billing method of your instance.
- You cannot release a subscription instance.
- If the instance has an unpaid order, you cannot upgrade the specifications of a subscription instance. You need to cancel this order on the Billing Management page and change the billing method of the instance to subscription.
