If you have set any custom configuration parameter values in the server.conf file, save those values in separate files before the upgrade.
To save your custom configuration information:
Log in to the Sentinel server as the novell user and go to the /etc/opt/novell/sentinel/config/ directory.
Create a configuration file named server-custom.conf and add your custom configuration parameters in this file.
(Optional) Create similar custom configuration files for other components of Sentinel, such as Netflow Collector. For example, netflow-collector-custom.conf.
Sentinel applies the saved custom configuration in these configuration files during the upgrade.
