Upgrading Vcs Software - Cisco TelePresence Administrator's Manual

Maintenance
New features may also become available with each major release of the System platform component, and
you may need to install new option keys to take advantage of these new features. Contact your Cisco
representative for more information on all the options available for the latest release of VCS software.
Installing and rebooting
Upgrading the System 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.
This means that you can upload the new software at any time, and then wait until a convenient moment (for
example, when no calls are taking place) to switch to the new version by rebooting the system.
Note: any configuration changes made between the software upload and the reboot will be lost when the
system restarts using the new software version.
The upgrade of components other than the System platform does not involve a system reboot, however the
services provided by that component will be temporarily stopped while the upgrade process completes.
