Devices available in different managed accounts

Hi people, How can claim a Device and make it available in more than one Managed account?

I don’t believe that is possible. When a device is onboarded into one account, you can move it to another account, but the device cannot be in both cnMaestro accounts at the same time.

I have an account which manages a big network. Now I need to reorganize this network and assign each smaller part of it of to different Users do monitor. How attend achieve this goal?
