Elastic Compute Service:ModifyPrepayInstanceSpec

The instance ID.

The region ID of the instance. You can call the DescribeRegions operation to query the most recent region list.

The new instance type. For information about available instance types, see Instance families or call the DescribeInstanceTypes operation.

The type of the change to the instance. Valid values:

• upgrade: upgrades the instance type. Make sure that the balance in your account is sufficient.
• downgrade: downgrades the instance type. When the new instance type specified by the InstanceType parameter has lower specifications than the current instance type, set OperatorType to downgrade.

The client token that you want to use to ensure the idempotency of the request. You can use the client to generate the value, but make sure that the value is unique among different requests. This value allows only ASCII characters and is up to 64 characters in length. For more information, see How do I ensure the idempotence of a request?

Specifies whether to enable automatic payment when you upgrade the instance type. Valid values:

• true: The payment is automatically completed.
• false: An order is generated but no payment is made.

Default value: true.

• Make sure that your account balance is sufficient. Otherwise, your order becomes invalid and must be canceled.

• If your account balance is insufficient, you can set AutoPay to false to generate an unpaid order. Then, you can log on to the ECS console to pay for the order.

• If you set OperatorType to downgrade, AutoPay is ignored.

Specifies whether to allow cross-cluster instance type upgrade. Valid values:

• true
• false

Default value: false.

When you set MigrateAcrossZone to true and you upgrade the instance type of an instance based on the returned information, take note of the following items:

Instance that resides in the classic network:

• For retired instance types, when a non-I/O optimized instance is upgraded to an I/O optimized instance, the private IP address, disk device names, and software authorization codes of the instance change. For a Linux instance, basic disks (cloud) are identified as xvd* such as xvda and xvdb, and ultra disks (cloud_efficiency) and standard SSDs (cloud_ssd) are identified as vd* such as vda and vdb.
• For instance families available for purchase, when the instance type of an instance is changed, the private IP address of the instance changes.

Instance that resides in a virtual private cloud (VPC): For retired instance types, when a non-I/O optimized instance is upgraded to an I/O optimized instance, the disk device names and software authorization codes of the instance change. For a Linux instance, basic disks (cloud) are identified as xvd* such as xvda and xvdb, and ultra disks (cloud_efficiency) and standard SSDs (cloud_ssd) are identified as vd* such as vda and vdb.

The new category of the system disk. Valid values:

• cloud_efficiency: utra disk
• cloud_ssd: standard SSD

The restart time of the instance. The time follows the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC.

The end time of the temporary change. The time follows the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC.

Specifies whether to restart the instance immediately after the instance type is changed. Valid values:

• true
• false

Default value: false.

Valid values:

• Online
• Offline
