The Upgrade Configuration feature helps you to upgrade the specifications of your Subscription instances to meet your business needs. However, you may have to pay the price difference for the upgrade. While you are changing the instance type, you can also perform any of the following operations:
Convert the billing method of cloud disks that are used as data disks from Pay-As-You-Go to Subscription. Note that you cannot change the billing method of system disks.
Adjust the Internet bandwidth of a VPC-Connected ECS instance that no EIP address is bound to or a classic network-connected ECS instance. You can use this feature to assign an Internet IP address to the instance.
The Upgrade Configuration feature has the following limits:
It is only applicable to Subscription instances.
You can use it to upgrade the specifications of vCPU and RAM simultaneously, but not separately, by changing the instance type.
Some instance types are not supported. For more information, see Instance type families.
It can be used to change Internet bandwidth of only VPC-Connected ECS instances that no EIP address is bound to and classic network-connected ECS instances.
It can be used to change the billing method of cloud disks that are used as data disks, but not that of system disks.
During the current billing cycle, if you have performed the Renew for Configuration Downgrade operation, you cannot upgrade configurations until the next billing cycle.
After you change the instance types or increase the Internet bandwidth of a classic network-connected ECS instance from 0 Mbit/s to a non-zero value for the first time, you must restart the instance in the ECS console or by using the RebootInstance interface for the new configuration to take effect.
This section introduces how to upgrade configurations in the ECS console. If you want to upgrade configurations by using the API, open a ticket to apply for permission in the whitelist.
To upgrade the configurations, follow these steps:
Log on to the
In the left-side navigation pane, click Instances.
Select a region.
In the instance list, find your instance, and in the Actions column, click Change Configuration.
On the Change Configuration Guide dialog box, choose Upgrade configuration.
Click Continue to go to the Upgrade Configuration page.
On the Upgrade Configuration page, perform any of the following operations:
- Select a new instance type. The page displays all the new instance types that are available for your instance.
- If a Pay-As-You-Go data disk is attached to your instance, you can convert its billing method to Subscription.
- Set a new value for the bandwidth.
Click Pay to complete the order.
If you have changed the instance type, or if you have increased the bandwidth from 0 Mbit/s for your classic network-connected ECS instance, restart the instance in the console or by using the RebootInstance interface.
You do not have to restart a VPC-Connected ECS instance if its bandwidth is increased from 0 Mbit/s for the first time.
