ApsaraDB for MongoDB:Change the billing method of an instance from pay-as-you-go to subscription

Prerequisites

• The instance uses the pay-as-you-go billing method and is in the Running state.

• The instance is of an available instance type. See Unavailable instance types for details.

  Note

  To change the billing method of an instance that is of an unavailable instance type from pay-as-you-go to subscription, change the instance type first.

• The instance runs MongoDB 4.0 or later.

  Note

  To change the billing method of an instance that runs a MongoDB version earlier than MongoDB 4.0 from pay-as-you-go to subscription, upgrade the database version of the instance. For more information, see Upgrade the major version of an instance and Update the minor version of an instance.

• The instance has no unpaid subscription orders.

  Note

  If you change the billing method of an instance from pay-as-you-go to subscription, a subscription order is generated. You cannot purchase a new instance or change the billing method of an instance to subscription until you pay for this order. You can log on to the Expenses and Costs page, and select Order Management > My Orders to complete the payment or cancel the order.

• Make sure that your Alibaba Cloud account has sufficient balance to pay for the subscription fee.

Usage notes

A subscription instance cannot be released.
