You can upgrade the edition of your Web Application Firewall (WAF) instance. You can also upgrade or downgrade the specifications of the value-added services that you purchased. This topic describes how to upgrade or downgrade a WAF instance.
Upgrade and downgrade
Supported WAF editions
You can upgrade or downgrade a WAF 2.0 instance of the following editions: On-cloud WAF Pro, On-cloud WAF Business, On-cloud WAF Enterprise, On-cloud WAF Exclusive, and Hybrid Cloud WAF Exclusive, regardless of whether the instance resides in the Chinese mainland or outside the Chinese mainland.
Upgrade
If your WAF instance cannot meet your business requirements, you can upgrade the instance to a higher edition before the instance expires. A WAF instance of a higher edition provides more enhanced protection. For more information about the features supported by each WAF edition, see WAF development plans and editions.
Log on to the WAF console. In the top navigation bar, select the resource group and the region in which the WAF instance is deployed. The region can be Chinese Mainland or Outside Chinese Mainland.
In the upper-right corner of the Overview page, click Upgrade.
On the Web Application Firewall | Upgrade/Downgrade page, configure the parameters, read and select Terms of Service, and then click Buy Now to complete the payment.
Downgrade
Unsupported scenarios
The value of the Extra Domain Package or Exclusive IP Addresses parameter must be greater than or equal to the number of additional domain names or exclusive IP addresses that you used. For example, you purchased an on-cloud WAF Pro instance and set the Extra Domain Package parameter to 2. The instance provides a default domain name quota of 10 and an additional domain name package quota of 2. If you added 12 domain names to the instance, the additional domain name quota of 2 in 1 additional domain name package is consumed, and you cannot modify the Extra Domain Package parameter to be less than 1.
You can perform a downgrade operation once a month.
Supported downgrade operations
Downgrade the specifications of value-added services
You can downgrade the following specifications of value-added services: extra bandwidth packages, extra domain packages, exclusive IP addresses, log storage capacity, and data visualization.
Disable value-added services
You can submit a ticket to disable the following value-added services: bot management, application protection, and API security.
Downgrade impacts
If your log storage usage exceeds the limit after a downgrade, new logs cannot be written, which will result in log loss. The minimum log storage capacity to purchase is 3 TB, and downgrading below this limit is not supported.
If you want to disable bot management, application protection, or API security by downgrading your WAF instance, submit a ticket.
Refunds
You can request a refund when you perform a downgrade operation. For more information about how to calculate refunds, see Rules for unsubscribing from resources.
You can calculate refunds by using the following formula: Refunds = Paid amount - Fees for consumed resources. Fees for consumed resources = Usage duration (days) × Daily unit price × 1.5.
Procedure
Log on to the WAF console. In the top navigation bar, select the resource group and the region of your WAF instance. You can select Chinese Mainland or Outside Chinese Mainland.
In the left-side navigation pane, choose Systems > Service Information.
In the upper-right corner of the basic information section on the Service Information page, click Downgrade.
On the Web Application Firewall | Downgrade page, configure the parameters, read and select Terms of Service, and then click Buy Now to complete the payment.
