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

Upgrade Instructions​

  1. Log in to NFO at https://<nfo-host>:8443.
  2. Click the Stop button at the top of the page.
  3. Ensure the Play button turns grey, indicating the service has stopped.

2. Apply the Update​

RPM Installation (Linux)​

  1. Copy the new RPM package to the server. Only <version> changes between releases; the rest of the file name is literal.

To upgrade in a custom directory, use: rpm -Uhv --relocate /opt=<new-path> flowintegrator-*-linux.x86_64.rpm.

TAR Installation (Linux)​

  1. Navigate to <installation_dir>/flowintegrator and run the uninstall command:
./setup.sh -u
  1. Uncompress the new installer:
tar zxvf flowintegrator-*-linux-x86_64.tar.gz -C <installation_dir>
  1. Navigate to <installation_dir>/flowintegrator and start the installation:
./setup.sh -i

Windows Installation​
