Change device image?

[rclimpson]

I noticed once a device is shutdown and you go to Edit, there is an option to select a different device image. I've tried this on some Juniper vMXs but the device always boots from the original image i selected when creating the device.

Is it possible to change a devices image or are you stuck with the initial one?

it is mandatory to do wipe node after you changed image.
right click --->wipe

Wipe means clean/delete previous saved image profile/NVRAM
