You will be disappointed as it does not explain how your real world problems are solved. You’re not in the business of collecting metric. Iwan ‘e1’ Rahabok made an impressive book on VMware vSphere Metrics and now is at its 4th edition!

Upgrading Horizon Connection Server from Windows Server 2016/2019 to 2022

5 August 2024

Reading Time: 3 minutesIf 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.
