What is the required firmware update path for 10ZiG thin and zero clients?
When performing a major version upgrade, i.e. from 16.3.x to 16.5.x, you must perform the upgrade using the best practice upgrade path.
From versions 16.1.x, 16.2.x, and 16.3.x, this path would be to first upgrade from your current firmware version to 16.3.35.5, and then upgrade from 16.3.35.5 to 16.5.x.
Upgrade from our legacy 12.x firmware to 16.x is no longer supported, and will require a reimage of the device to the latest firmware.
NOTE: When performing any major version firmware update, is it always required to perform a full factory default after the update process. Do not use the check box in your Manager’s firmware update wizard for this; instead perform a factory default as a scheduled task after the update has been applied to the device.
Once the factory default is performed, you can then apply a configuration template created from the target firmware version to your newly updated devices. Do not attempt to use the configuration templates created on your previous firmware as they will not work and could leave your devices in an unusable state.
