This topic shows you how to upgrade a KAD instance.
Anti-DDoS capability: Upgradable. After the upgrade, the free back-to-origin bandwidth and highest capability increase accordingly.
Highest capability: All instances can be upgraded. After the upgrade, the highest anti-DDoS capability increases accordingly.
The upgrade configuration takes effect immediately.
KAD instances are billed on a daily basis at the new package price from the day when the upgrade takes effect. For example, if you activate a one-month 30 Gbit/s package on January 1, which is upgraded to 100 Gbit/s on January 10, then the billing will be based on the daily price of the 30 Gbit/s package from January 1 to 9, and on the daily price of the 100 Gbit/s package from January 10 to 30.
In the dialog box that appears, set parameters as needed.
