In this release, endpoints cannot be deleted from the MC. As a workaround, you can create a new group specifically for the endpoints you wish to delete, move, them into this group, and then delete this temporary group. The endpoints will be returned to the UNGROUPED table.
Note: Once an endpoint is managed by an MC, you must clear the endpoint’s management state from the AWI before it will accept a new one. To change the MC that will manage an endpoint, you can then reconfigure your DHCP server or DNS server with a different MC IP address/FQDN or you can manually reconfigure a new MC.
