If you are are planning to upgrade your Horizon Connection Server’s OS, there are two different paths. One is using an in-place upgrade of Windows Server that can work (in theory). The second one is decommisioning your connection server and replace with a new one (and repeat if you have more).

The strategy really depends of the size of your environment and how much is production critical.

With a dev or lab environment single server, the in-place OS upgrade could make sense.

Debian like distributions have a nice option to manage distribution upgrade (apt-get dist-upgrade), not available on RedHat like distributions… in-place upgrade are still possible, but maybe much more tricky and sometimes not supported at all.

For Rocky Linux in-place upgrades from one major version to the next aren’t supported (see https://docs.rockylinux.org/release_notes/9_0/) at all and there is a good reason… if somethings goes wrong you cannot revert the operation. There are also other good reasons, like that the new version may require more resources (for example, disk space).

The vCenter Server Security Token Service (STS) is a Web service that issues, validates, and renews security tokens.

As a token issuer, the Security Token Service (STS) uses a private key to sign the tokens and publishes the public certificates for services to verify the token signature. vCenter Server manages the STS signing certificates and stores them in the VMware Directory Service (vmdir). Tokens can have a significant lifetime, and historically might have been signed by any one of multiple keys.
