On RDS hosts with Windows Server 2012 R2 or later, you can upgrade the Horizon Agent software and edit pool settings so that the RDS host can provide remote desktops and remote Windows-based applications.
Prerequisites
- Verify that at least one Horizon Connection Server instance in the replicated group has been upgraded. Connection Server must be upgraded first so that the secure JMS pairing mechanism can work with Horizon Agent.
- Verify that the RDS host currently hosting remote desktops is running a supported version of Windows Server operating systems. If you do not have a supported Windows Server operating system, you must do a fresh installation rather than an upgrade. For a list of supported operating systems, see Requirements and Considerations for Horizon Agent.
- Verify that the RDS Host role is installed in the operating system. See the procedure called "Install Remote Desktop Services" in the Windows Desktops and Applications in Horizon 8 document.
- Familiarize yourself with the procedure for running the Horizon Agent installer. See the procedure called "Install Horizon Agent on a Remote Desktop Services Host," in Windows Desktops and Applications in Horizon 8, available by clicking the Help button in Horizon Console.
- Verify that you have logged off from all remote desktops and remote applications.
- Verify that you have a domain user account with administrative privileges on the hosts that you use to run the installer and perform the upgrade.
