Current set up:
----------------
Sly multiroom sub: Main viewing card in my Enigma box, multiroom card in my Sly+HD box
+ a sub to BT Sports HD with multiroom (both my Sly viewing cards have BT Sports paired to them)
Octo-Lnb (serves 3rd party boxes and current Sky+HD box)

Question:
----------
If I upgrade to Sly Q, what happens to my existing Sly boxes & viewing cards, BT Sports subs (multiroom) etc. are they redundant?
presumably I ask for a hybrid lnb to service my 3rd party boxes


1) Does Sly Q "replace" both my existing Sly Viewing cards and boxes? or is it along side them?
2) If I already have Sly multiroom does Sly Q replace the multiroom box and its viewing card as well or do they provide Q mini boxes?
3) what do I do with my BT Sport multiroom sub, do I still need BT multiroom to view BT Sports on multiple Q boxes because there is one Q card.

bit confused here, has anyone been through this?
