If I Change the OS of a Protected Server, Does It Affect My HSS Quota?

No. But before changing the server OS, you need to check whether the HSS agent supports the new OS. To obtain better HSS service experience, you are advised to install or upgrade to an OS version supported by the agent.

HSS agents can run on Linux servers, such as CentOS and EulerOS; and Windows servers, such as Windows 2012 and 2016.

The agent is probably incompatible with the Linux or Windows versions that have reached end of life. To obtain better HSS service experience, you are advised to install or upgrade to an OS version supported by the agent.
