Upgrading to Sky Q - full system overhaul?

[Tubblerone]

I've recently had a letter from Sky saying they're phasing out the HD boxes we currently have in the rack and are offering a free upgrade to Sky Q, so I'm trying to get a handle on what needs to be done in order for this to work within my set up which consists of the following:

HC250 Controller (software version 2.10)
SR250B Remote
Wyrestorm MX 0404-QI Matrix

I'm aware the matrix is only an HD output and will not see the benefit of the Sky Q Ultra and the controller is fairly old and needs a substantial software update. On top of this I would think I need new drivers installed for the Sky Q to work as well.
We currently have 2 x HD boxes in the rack so people can watch different content in different rooms but I'm struggling to get my head round how we would replicate this scenario with Q - do we need a main box and a hub?

With all this in mind, what stumbling blocks can you foresee with this set up and what would you recommend?
I'm toying with the idea of updating the controller to an EA-3 and the matrix to something like a C4-LU642 (both second hand) and the remote seems to be on its last legs too although I think it may just need a new battery.
With the matrix, would I be able to use the baluns from the old matrix, or would they need updating too?

Any thoughts or suggestions welcome.

I cannot fully comment on SkyQ install as such, but a brief glance just tell me you'd get two new SkyQ UHD boxes to replace existing boxes (and possibly a dish upgrade).

System software wise, it would just be two new drivers - no major upgrade required as such, though to get 3rd party developed IP drivers, you may need to be at a certain version.

 

Depending on the requirements for the boxes to use on demand etc, it's possible there needs to be an update to your network, or at least a rewire/rework.

 

If you're getting a new video switch, you'll need the baluns as well - it's unlikely the MX 0404 baluns will work with an LU at least.
