Last updated: 2020-06-28 09:53:26

    How do I upgrade/downgrade the configurations of CVMs?

    You can only adjust the configurations of instances whose system disks and data disks are both cloud disks.

    If your configuration adjustments do not take effect, please submit a ticket to contact us.

    How do I check the records of configuration adjustments?

    1. Log in to the CloudAudit Console.
    2. On the Event history page, set filters such as the username, the resource type, and the resource name as needed to view the record list.
      For more information, see Getting Started.

    Can I adjust the configurations of CVM instances?

    Yes. You can adjust the configurations of instances whose system disks and data disks are both cloud disks. For pay-as-you-go instances, you can upgrade or downgrade their configurations as many times as you want.

    What is the maximum number of times I can downgrade the configurations of CVMs?

    • You can upgrade or downgrade the configurations of pay-as-you-go instances as many times as you want.

    Can I upgrade the specifications and the configurations of pay-as-you-go instances?

    Yes. You can upgrade the configurations of pay-as-you-go CVM instances by following the directions listed in Changing Instance Configurations or through the ResetInstancesType API.

    How long does it take to upgrade a CVM instance?

    About 1 to 2 minutes.

    How is the cost incurred for a CVM instance upgrade calculated?

    You can view the cost details at the Billing Center after you upgrade the specifications or the configurations of the CVM instance.

    Will upgrading CVM instances affect my business configurations on the instance?

    After you upgrade a CVM instance, you must restart it to validate the new configurations. The upgrade operation will interrupt your business for a short period of time. We recommend that you upgrade instances when business is slow. After being upgraded, instances will seamlessly resume your business and will not require environment reconfiguration.

    Why is the estimated refund of a CVM downgrade 0?

    One possible reason is that you have purchased the instance at a discount but the downgraded configuration is calculated according to the original price of the instance. When the price of the instance purchased at a discount is lower than or equal to the original price of the instance, the estimated refund will be displayed as 0.

    Why did the instance upgrade not take effect?

    After you upgrade an instance, you must restart it on the Console or through an API.
