Perform a vCenter Server upgrade as part of the same maintenance window during which you upgrade other View server components. Before you upgrade vCenter Server, you must back up some View data. After the upgrade, if View Composer is running on the same server, you must restart the View Composer service.

Determine when to perform this procedure. Choose an available desktop maintenance window. For information about how much time is required, see the VMware vSphere Upgrade Guide.

Back up the vCenter Server database and the View Composer database.

Back up the View LDAP database from a View Connection Server instance by using the vdmexport.exe utility.

For instructions, see the VMware Horizon View Administration document. If you have multiple instances of View Connection Server in a replicated group, you need to export the data from only one instance.

Perform the tasks listed in Preparing for Upgrades That Include vSphere.

Verify that the server on which vCenter Server is installed has a CA (certificate authority)-signed SSL server certificate installed and configured. After you upgrade View Connection Server, if vCenter Server does not use a CA-signed certificate, the default self-signed certificate is shown as invalid in View Administrator, and a message indicates that vCenter Server is unavailable.

Complete the prerequisites listed in the VMware vSphere Upgrade Guide, using the version of the guide that corresponds to the version of vSphere that you plan to upgrade to.


Upgrade vCenter Server as described in the VMware vSphere Upgrade Guide.


If View Composer is installed on the same host, restart the View Composer service.


Log in to View Administrator and examine the dashboard to verify that the vCenter Server and View Composer icons are green.

If either of these icons is red and an Invalid Certificate Detected dialog box appears, you must click Verify and either accept the thumbprint of the untrusted certificate, as described in "What to Do Next," or install a valid CA-signed SSL certificate.

For information about replacing the default certificate for vCenter Server, see the VMware vSphere Examples and Scenarios document.

To use a default or self-signed certificate from vCenter Server or View Composer, see Accept the Thumbprint of a Default SSL Certificate.

If you use Horizon View Client with Local Mode, see Upgrade View Transfer Server.

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.
