Upgrading And Option Keys; Installing And Rebooting; Upgrade Procedure - Cisco TelePresence Administrator's Manual

Upgrading and option keys

All existing option keys are retained through the upgrade from one version of the VCS platform to the next,
including upgrades to the next major release. However, you are recommended to take note of your existing
option keys before performing the upgrade.
New features may also become available with each major release of the VCS 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 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.
This means that you can upload the new software to your system at any time, and then wait until a
convenient moment (for example, when no calls are taking place) to install 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 VCS platform does not involve a system reboot, however the
services provided by that component will be temporarily stopped while the upgrade process completes.
