This procedure shows how to use View Administrator to change the message security mode to Enhanced and monitor the progress of the change on all View components. You can alternatively use the vdmutil command-line utility to change the mode and monitor progress. See the View Administration document.
To use Access Point appliances instead of View security servers, you must upgrade the View Connection Server instances to version 6.2 or later before installing and configuring the Access Point appliances to point to the View Connection Server instances or the load balancer that fronts the instances. For more information, see Deploying and Configuring Unified Access Gateway.
Verify that you have upgraded all View Connection Server instances, security servers, and View desktops to Horizon 6 version 6.1 or a later release. View components that predate Horizon 6 version 6.1 cannot communicate with a View Connection Server 6.1 instance that uses Enhanced mode.
