You can use the Software Upgrade option to upgrade your NetScaler SD-WAN Center software to the latest version. The software upgrade process places NetScaler SD-WAN Center into maintenance mode. If a database migration is required, this process can take several hours. During this time, no statistics data will be collected from the Virtual WAN, and all NetScaler SD-WAN Center functionality will be unavailable.
Running the upgrade during maintenance hours is recommended.
Download the appropriate NetScaler SD-WAN Center software package to your local computer. You can download this package from Downloads page.
