TTG-239 is on my prime YouView DN370T.02.04.P which I want to be my receiver of subscribed channels

Since I upgraded to PlusTV I have been able to receive the subscibed SKY channels on both the EssentialsTV box and PlusTV player.  The PlusTV player has now been disabled but I want to have this device (DN370T.02.04.P), the recording YouView, to keep the Sky channels and disable the Essentials box (DN360T.01.02.P) now that I have received the TTG-239 message.
