Change the billing method of instances from pay-as-you-go to subscription

Precautions

• The billing method of subscription-based instances cannot be changed to pay-as-you-go. To prevent resource waste, determine whether you need to change the billing method of your resources.
• You cannot release subscription-based instances.
• You cannot update the specifications of the instance if you have an unpaid subscription-based instance. You need to cancel this order on the Orders page and change the billing method of the corresponding instance to subscription.

Prerequisites

• The instance is in the running state.
• The billing method of the instance is pay-as-you-go.
• You do not have an unpaid subscription-based instance.
• The instance type cannot be phased-out types (that is, instance types are no longer available for sale). For more information about phased-out instance types, see the Instance types displayed before July 10, 2017. If you need to change the billing method of a phased-out instance type to subscription, change the instance type first. For specific operations, see Change the configuration.
