Upgrading OneController

After the initial installation (see Installing and Setting Up OneController), you can upgrade OneController with updated images available at https://extranet.extremenetworks.com/downloads/ Pages/OneController.aspx on the Software tab.

The upgrade images have the following extensions:

• OneC-V Controller image extension: jse
• OneC-A-600 Controller image extension: ice

The configuration directories that are copied during a backup (see Backing Up and Restoring Configurations and Logs) are copied before an upgrade starts. The platform configuration is restored upon completion of the upgrade.

Caution

The OneController configuration directories are restored to /usr/opendaylight/preserved when an upgrade finishes. Because OneController is based on the OpenDaylight controller, whose development is not controlled by Extreme Networks, the compatibility of your current configuration files with new OneController image cannot be assured. After the upgrade is complete, use a file compare utility to examine differences between your old backup configuration files in the preserved directory with the new configuration files in/usr/opendaylight/configuration/ that were installed by the upgrade. Make changes to the new configuration files as needed.

1. On the left navigation bar, click System Configuration, and then, on the menu bar, click Maintenance. The Maintenance System screen appears (see the following figure).
