Selective Software Update

You can deploy two major releases of Oracle SD-WAN Edge within a single network using Selective Software Update. This avoids a global outage when updating the entire SD-WAN; some appliances update, while other devices continue to operate. Selective Software Update lets you update the Edge devices in your network on a rolling basis, by selecting sites and identifying update time. Each software release has a compatibility matrix that details backwards compatibility for prior releases of Oracle SD-WAN Edge. This compatibility matrix can be found in the Release Notes.

You may upgrade and downgrade between two sequential major releases, and can also schedule upgrades/downgrades on a per-site or a site-group level. When upgrading an HA pair by Selective Software upgrades, both peers will be upgraded to the same target version.

When two versions of the Edge software are deployed within your APN, the Configuration Editor will only allow you configure settings that are common to both versions. Later, when all sites are upgraded to the same Edge version, all features may be configured.
