Installing and rebooting
Upgrading the VCS platform component is a two-stage process. First, the new software image is
uploaded onto the VCS. At the same time, the current configuration of the system is recorded, so that
this can be restored after the upgrade. During this initial stage the system will continue running on its
existing software version, and all normal system processes will continue.

The second part of the upgrade involves rebooting the system. It is only during the reboot that the VCS
installs the new software version and restores the previous configuration. Rebooting causes all current
calls to terminate, and all current registrations to be ended.
