Tata Sky — Regarding closure of one set top box services

I've 2 set top boxes for Tata Sky broad band services. One set box has recording facility and other set top box doesn't have one. Now I want to stop services of set top box which doesn't have recording facility. Every time we want to make changes, Tata shy replies that they will delete all recordings if any switch happens. This is not understandable. The recordings are on set top box. How can the switching should affect the recording? This is clear cut way of discouraging any changes.
