Upgrading or Removing NFO

This guide provides the necessary steps to upgrade your NetFlow Optimizer (NFO) instance to the latest version or remove it from your system across all supported platforms.

Upgrading NFO​

You upgrade a single instance of NFO by installing the latest version over your existing installation. During this process, the installer preserves all NFO configurations except for configuration files that were changed manually.

Configuration Backups

If configuration files were manually modified, they are backed up into a conf-backup.<date>.tar.gz archive. You should restore these manually after the upgrade if necessary.

Common Configuration Files​

The following files are often subject to manual changes and should be verified after an upgrade:

FilePurpose
$NFO_HOME/tomcat/bin/setenv.shEnvironment variables
$NFO_HOME/tomcat/conf/.tomcat_keystoreDefault self-signed certificate
$NFO_HOME/tomcat/conf/.truststoreExternal Data Feeder for NFO certificate
$NFO_HOME/tomcat/conf/server.xmlKeystore password
$NFO_HOME/server/etc/server.cfgServer and some Web GUI configurations
$NFO_HOME/java/jre/lib/security/cacertsTrusted certificates imported into Java Runtime
