Well I have 5 tata sky connections from two sub ids. 4 connections on one sub id and one from 2nd sub id. At present i am going to shut down my 2 connections as i need only 3 at present. But my one hd stb from 2nd sub id is 2018 model new one. I want to swap that box to my 1st sub id as i want to use that new box. Is it possible in tata sky. Please help.
