Editor to share with you how to change the system disk or operating system of an ECS instance. I hope you will gain a lot after reading this article. Let's discuss it together.

ReplaceSystemDisk

Description

When calling this interface, you need to be aware of:

You cannot change the disk type of the system disk.

Changing the system disk cannot change the disk type and payment method, but it will change the disk ID of the system disk, and the original disk will be released.

The state of the instance must be stopped (Stopped). If your private network VPC instance enables the no charge feature for instance downtime in VPC, in order to prevent the instance cannot be restarted after replacing the system disk due to insufficient ECS instance resources in the region, you need to disable the no charge feature when stopping the instance. See StopInstance for more details.

The OperationLocks of a security-controlled ECS instance cannot be marked "LockReason": "security".

The instance cannot be in arrears.

You can re-specify the capacity size of the system disk through the parameter SystemDisk.Size. The value of SystemDisk.Size must be greater than or equal to max {20, the current system disk capacity}. An extra charge will be charged for the portion of disk capacity that exceeds max {20, the capacity of the system disk before replacement.
