Change management for VPX instances

Last published : Sep 03, 2026
You can track any changes to the configuration on a NetScaler VPX instance from the Management Service. The details pane lists the device name with IP address, date, and time when it was last updated. It also lists whether there is any difference between the saved configuration and the running configuration. Select a device to view its running configuration, saved configuration, history of configuration changes, and any difference between the configurations before and after an upgrade. You can download the configuration of a VPX instance to your local computer. By default, the Management Service polls all the instances every 24 hours, but you can change this interval. You can create an audit template by copying the commands from an existing configuration file. You can later use this template to find any changes in the configuration of an instance and take corrective action if necessary.

To view change management for VPX instances

  1. On the Configuration tab, navigate to NetScaler > Change Management.
  2. In the Change Management pane, select a VPX instance, and then from the Action list, select one of the following:
    • Running Configuration—Displays the running configuration of the selected VPX instance in a new window.
    • Saved Configuration—Displays the saved configuration of the selected VPX instance in a new window.
    • Saved Vs. Running Diff—Displays the saved configuration, the running configuration, and the corrective command (the difference).
    • Revision History Diff—Displays the difference between the base configuration file and the second configuration file.
    • Pre vs. Post Upgrade Diff—Displays the difference in the configuration before and after an upgrade, and the corrective command (the difference).
    • Template Diff—Displays the difference between the saved or running configuration and the template. You can save this difference as a batch file. To apply the configuration from the template to the instance, apply this batch file to the instance.
    • Download—Downloads the configuration of the selected VPX instance and saves it on a local device.
