Upgrading via System Update in the NSv Management Console

When you upgrade using System Update, SonicCore is updated as well as SonicOS. All configuration and registration settings are retained.

When upgrading a High Availability pair using System Update, upgrade each unit individually.

You can access the orange NSv management console by opening the virtual console from your hypervisor or by connecting to it with SSH, and then pressing Ctrl+s followed by the spacebar, if needed.

To upgrade your NSv using System Update

1. Select System Update in the left pane of the NSv management console.

2. Check for available system updates. Press the Tab key to move to the right pane, and use the arrow keys to select Start Update and then select Yes and press Enter.

3. If a new version is available, it is displayed in the center of the screen. Select Start update and then press Enter. The update version will begin to download and can take a few minutes or, in some cases, a few hours.

   Do not power off or reboot during the download.

4. If you want to close the downloading progress display, press the ESC key. This allows you to move around the NSv management console or switch to the SonicOS CLI console with Ctrl+spacebar. SonicOS continues to run during the download.

5. When the download completes, the message Reboot to complete update is displayed in the NSv management console. Press ESC to close the status display.

6. Select Reboot | Shutdown in the left pane, then select Reboot in the right pane and select Yes and press Enter to start the reboot process.

   You can reboot from the NSv management console as shown here, or from the VM menu. However, DO NOT reboot from the SonicOS web management interface or the CLI – those methods will reboot to the old version.

   After the reboot but before SonicOS comes up, the Initializing services message is displayed. Do not power off or reboot again until this completes.

   

7. When SonicOS comes up, view the About screen in the orange NSv management console to verify that SonicCore is updated.

8. Switch to the SonicOS console to verify that SonicOS is updated to the new version, and that the NSv is still registered and X0 still has the configured IP address.

   

   The system might require two or three minutes to mark the update as successful. To avoid rolling back to the previous SonicCore version during a subsequent reboot, wait a couple of minutes before rebooting the system again.
