2 Operating System Upgrade from the NCN

When you need to upgrade the Oracle SD-WAN Edge operating system (OS) on any of your SD-WAN appliances, use the Oracle SD-WAN Edge Network Control Node (NCN) User Interface (UI) to guide you through the process. The UI provides a central location for conducting the upgrade process across your network of SD-WAN appliances. You can upload OS packages and remotely upgrade OS versions for all supported hardware, virtual platforms, and cloud platforms from the same UI console you use to upgrade the software.

Beginning with the 9.1.0m1 release, Oracle SD-WAN Edge supports:
  • upgrading all sites to a specified OS version.
  • upgrading any single site to a specified OS version.
  • choosing a subset of remote sites for upgrade.
  • upgrading HA and GEO NCN peer sites.
  • updating a new OS image lower than the current Active OS version for a site.
  • rebooting and restarting all appliances from the NCN.
  • providing an overall view of the existing primary and secondary partitions, and the active and standby OS versions of all SD-WAN appliances.
  • displaying the status of the installation, switching OS, rebooting, and OS transfer for all sites.

Note:

All SD-WAN appliances must use the 9.1m1 version of the software to allow OS upgrades through the Centralized OS Upgrade function on a NCN. You cannot upgrade a client running an older version of the software with the Centralized OS Upgrade function.
As you move through the work flow, the system
  1. distributes the OS image to all specified SD-WAN Edge devices.
  2. installs the OS on the back up partition for the specified SD-WAN devices.
  3. switches the Backup partition to Active partition.
  4. reboots the SD-WAN devices.
  5. installs the OS on the HA standby and GEO NCN sites, if any, so that those sites synchronize with other devices.
