Sky Q codes / Custom codes transfer to V6

Hello,
I’m trying to successfully migrate to V6.
I had a custom code set for Sky Q device as this wasn’t originally available. It appears it is now a standard device but I can’t get it to work. Can anyone confirm how they’ve set up Sky Q in V6?

Alternatively, how do you migrate custom device codes from V5 to V6? I’ve also got some custom IP codes I’ve programmed for a Marantz receiver and I’d like these to transfer over.

thanks
