After you upgrade View Connection Server, you can upgrade the security servers that are paired with it.

Determine when to perform this procedure. Choose an available desktop maintenance window. Budget 15 minutes to half an hour for each instance.

Verify that you have upgraded View Connection Server. For instructions, see Upgrade View Connection Servers in a Replicated Group.

Verify that the virtual or physical machine on which the current security server is installed meets the system requirements.

See View Connection Server Requirements.

Familiarize yourself with the security-related requirements of Horizon View, and verify that these requirements are met. See Upgrade Requirements for View Connection Server. You might need to obtain and install a CA-signed SSL server certificate that includes certificate revocation information, verify that Windows Firewall with Advanced Security is set to on, and configure any back-end firewalls to support IPsec.

Verify that you have a domain user account with administrative privileges on the hosts that you will use to run the installer and perform the upgrade.

If you have not configured a security server pairing password, use View Administrator 5.2 to do so. The installation program will prompt you for this password during installation. See the topic called "Configure a Security Server Pairing Password" in the VMware Horizon View Installation document.

If you are upgrading a View 5.1 or later security server, such as for a maintenance release, remove existing IPsec rules for the security server. See Prepare to Upgrade or Reinstall a Security Server.

You do not need to make any changes to the configuration of existing load balancers.


Run the installer for the Horizon View 5.2 Connection Server.

The installer determines that an older version is already installed and performs an upgrade. The installer displays fewer installation options than during a fresh installation.

You will be prompted to supply the security server pairing password.

You might be prompted to dismiss a message box notifying you that the Security Server service was stopped. The installer stops the service in preparation for the upgrade.


After the installer wizard is finished, verify that the VMware View Security Server service is started.


Log in to View Administrator, select the security server in the Dashboard, and verify that the security server is now at version 5.2.


Verify that you can log in to a View desktop.


In View Administrator, go to View Configuration > Servers > Security Servers tab and remove any duplicate security servers from the list.

The automated security server pairing mechanism can produce duplicate entries in the Security Servers list if the full system name does not match the name that was assigned when the security server was originally created.

Upgrade the other View server components, such as vCenter Server and View Transfer Server, if you use any of these components. See Upgrading Horizon View Server Components.

If you have finished upgrading View server components, at your next maintenance window, continue with the Horizon View upgrade.

If you are also upgrading vSphere components, see Upgrade ESX/ESXi Hosts and Their Virtual Machines.

If you upgrading only Horizon View components, see Upgrade View Agent.
