Restoring the Previous Software Image

If for some reason you need to undo the upgrade, perform the upgrade again except:
• Specify the locations of the upgrade software image and configuration files.
then
• Specify the locations of the original software image and configuration files.

Upgrading ICSR Chassis

The procedure for upgrading primary and backup ICSR chassis is described in Interchassis Session Recovery.
Essentially the procedure requires upgrading the primary and standby chassis using the off-line method while
each is in standby mode.

Performing Dynamic Software Updates

StarOS allows the runtime loading of plugins. All StarOS builds include a "default" baseline plugin.
This feature is currently used to dynamically update the detection logic used to filter P2P applications via the
Application Detection and Control (ADC) feature.
Patching is the process used to install a plugin as an incremental update to a StarOS release. One plugin can
be provided to multiple, compatible, concurrent product releases. A plugin is distributed in the form of a
compressed distribution kit via the internet or by other means (USB stick, CD, etc.).
