Hello,  
I’ve a jetson tx2 which is running on `warrior` branch, now I want to upgrade the device to `dunfell`.  
I have generated a dunfell based image for my device. I’ve following error when I tried to install the artifact, has anyone had this issue before.

How to upgrade the BUP safely while upgrading from warrior to dunfell?

My understanding is that this is not possible with the Jetson platform. See [this topic](https://hub.mender.io/t/mender-standalone-update-from-warrior-to-zeus-or-dunfell/3516/6) for more background.
