Preparing Omnissa Horizon Connection Server for an Upgrade

Before you upgrade Horizon Connection Server or before you upgrade any of the vSphere components that Horizon Connection Server relies on, you must perform several tasks to ensure that these upgrades are successful.

Tasks to Perform on Only One Instance in a Replicated Group

Before you begin upgrading any Horizon Connection Server instances, perform the following tasks using only one of the instances. Because the instances are replicated, the settings on one instance are the same as the settings on the others:

• If Horizon Connection Server is installed in a virtual machine, take a snapshot of the virtual machine.

  For instructions on taking snapshots, see the vSphere Client online help. If you ever need to revert to this snapshot and if you have other Horizon Connection Server instances in a replicated group, you must uninstall those instances before you revert the golden image to the snapshot. After you revert, you can reinstall the replicated instances and point to the instance you reverted.

• Use the vdmexport.exe utility to back up the Horizon LDAP.

  For instructions, see the administration guide for your current version of the Omnissa Horizon 8 Administration document.

Tasks to Perform for Each Instance Just Before Upgrading

• Verify that the virtual or physical machine on which the current Horizon Connection Server instance is installed meets the system requirements for the new version.

  See Horizon Connection Server Requirements.

• Document the IP address and system name of the machine on which Horizon Connection Server is installed.

• Determine if your company has written any batch files or scripts that run against the Horizon LDAP database on the Horizon Connection Server instance, and if so, document their names and locations.

• Open Horizon Console and document all the settings that are specific to this instance.

  For example, go to Settings > Servers > Horizon Connection Servers, select the Horizon Connection Server instance in the table and click Edit. You can take a screen shot of each tab in the Edit Horizon Connection Server Settings dialog box.
