Before you upgrade security servers, perform these tasks to create backups and record configuration settings.
Verify that the virtual or physical machine on which the current security server is installed meets the system requirements for the new version.
If the security 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. You can label the snapshot Upgrade Preparation Phase.
Open Horizon Administrator and document the settings for this security server. Go to Security Servers tab.and click the
For example, select the security server, click Edit, and take a screen shot of the settings.
