If you are using different services on one server, the upgrade updates the services in the proper order.
For example, if your site has website and manager services on the same server, select both for update.
The upgrade installer applies the updates in the proper order. You must complete the upgrade on one
server before you begin an upgrade on another.
Note If your deployment uses a load balancer, the first appliance you plan to upgrade must be
connected to the load balancer. All other instances of vRealize Automation appliance must be disabled for
load balancer traffic before you apply the upgrade to avoid caching errors.
