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.
