Can I Change WAF Specifications During Renewal?
No. You can renew your cloud WAF instance, but you cannot change its specifications during renewal. You can renew your subscriptions to the current WAF edition, purchased domain, QPS, and/or rule expansion packages. If you need to change the WAF specifications during the renewal, Changing the Edition and Specifications of a Cloud WAF Instance and complete a renewal.
You can change specifications of your WAF instance as follows before you renew it:
- Upgrade WAF specifications
- Upgrade your WAF instance from the current edition to a higher edition.
- Increase the quantity of domain name, QPS, or rule expansion packages.
For details, see Changing Cloud WAF Edition and Specifications.
- Decrease WAF specifications
- Unsubscribe from your current instance edition and subscribe to a lower edition
- Decrease the quantity of domain name, QPS, bandwidth, and/or rule expansion packages.

To reuse the configurations of a WAF instance, ensure that the original WAF instance you unsubscribed from and the new WAF instance you are purchasing are in the same region. If you buy a WAF instance again after an unsubscription, you still need to add the domain name to the new WAF instance and configure protection rules for the domain name based on protection requirements. For details, see Can WAF Save Configurations for Me When I Unsubscribe from WAF?
