How to Perform a Software Upgrade
You can use the Software Upgrade option to upgrade your SD-WAN Center software to the latest version. The software upgrade process places 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 SD-WAN Center functionality will be unavailable.
Running the upgrade during maintenance hours is recommended. Note
Download the appropriate SD-WAN Center software package to your local computer. You can download this package from https://www.citrix.com/content/citrix/en_us/downloads/cloudbridge.html.
To upload and install a new version of the SD-WAN Center software
In the SD-WAN Center web interface, click the Administration tab.
Click Global Settings and then click Software Upgrade.
Click Browse to open a file browser, and select the software package you want to upload.
Click Upload to upload the selected software package to the current SD-WAN Center virtual machine.
After the upload completes, click Install.
When prompted to confirm, click Install.
In the dialog box that appears, select the I accept the End User License Agreement checkbox, and then click Install.
