Here is my situation. I have been on 7.3.2 on a WHS (Tranquil) I somehow managed to get Musicip headless set up. Also use the amazingly good Spicefly SugarCube. I rip, then I load into MusicIP by web interface and validate, then SqueezeCenter auto loads from the MusicIP system (I think) How sad is that I don't really know how it works. But it does very well! I also use ipeng on ipod touch. Over all everything works great, apart from the odd drop out on my bedroom SB3 in wireless.

So the question. If I upgrade to 7.5, will all this break?
My concerns are:
1. issues I've read on here about WHS installs not auto-starting on a reboot.
2. will SugarCube work with 7.5
3. will musicip headless still feed SC correctly

Anyone who has a similar set up, I would really value their experience.
Also, if there are any precautions I should take in the event I need to go back.

Thanks all for any help.
