Passing along some notes from our TAC engineers on doing this upgrade:
• For any Windows VIA 1.X users, they must upgrade to VIA 2.x.
• In AOS 5.X, VIA was packaged as part of the AOS image itself, so customers may not be able to upload the new binaries to the controller. Hence, we must turn OFF the ‘Allow client to auto-upgrade’ to ensure all clients don’t try to automatically update.
• In AOS 6.X, VIA can be updated on AOS using ‘Advanced Services > VPN Services > VIA’
If administrators don’t update the controller-hosted VIA image, then we must turn OFF the ‘Allow client to auto-upgrade’ to avoid downloading the old versions as the clients are already updated.
VIA 2.0.x Instructions for Upgrade
As upgrade was not supported in this release (allowing users to upgrade by double-clicking the MSI file), users must manually uninstall and install this new version.
Note – Administrator privileges are required to do uninstallation and installation. Also, we will need to reboot (User will be prompted) after uninstallation before proceeding to installation.
Note2 - It is possible to upgrade VIA 2.0 from the command line or through a batch script using the following:
> msiexec REINSTALL=ALL REINSTALLMODE=vamus /qr /i ansetup.msi
VIA 2.1.X Instructions for Upgrade
Upgrade is supported in this release. User must double-click on the executable, or choose "Run" when downloading through a browser, to update to this version.
