Hello,
Thank you for your question.
At the moment we don't have a function to move a device from one company to another company. If you want to move a device to the other company you will need to unregister that device from your RMS and then register it to the other company.
To unregister the device you don't need to have remote or physical access, for adding the device to the other company you will need the device's Serial number, LAN MAC or IMEI (depends on device type).
Let me know if you need further help.
Kind regards,
Edvinas
