Eyeglass operation will be interrupted briefly during Upgrade for an Eyeglass service restart
It is recommended to take a VMware snapshot to backup the Eyeglass appliance prior to applying an update.
For Eyeglass updates, when more than one Eyeglass package update is available they all must be applied as there may be dependencies between the packages requiring all updates for Eyeglass to function properly. (Eyeglass packages begin with "eyeglass" in the package name.) If prompted, you must also say yes to external dependencies.
