Upgrade to new SonicWall VPN

We have identified an issue with our new Sonicwall VPN that is impacting a number of users. A fix will be applied on Tue 12 Feb between 07:15-07:45 that will require a number of reloads of the VPN and result in disruption for all users of it. The VPN service should be considered at risk up until 09:00 on the day.

Post-upgrade update
We initially thought all users would need to delete and re-install the client to take advantage of the fix. Post-upgrade testing has shown this only applies to people on Windows 10 devices.
