Moving devices from one application to another using CLI

Is it possible to move devices from one Application to another one using the CLI?

I’ve tried:

./ttn-lw-cli end-devices set existing-app eui-xxxxxxxxxxxxxxxx --application-id new-app

“existing-app” has the device with that ID in it, “new-app” exists with no devices in it.

I get this warning and nothing happens (device remains in “existing-app”).

Is what I’m trying to do not possible?

WARN No fields selected, won't update anything

I would like to move several 100 devices into an app with a different ID. Deleting them is OK but moving would be much better!
