Well... What I did this year and will be doing, as this is my first year of breeding is I brumated my adults for 2 months from mid november to mid anuary, but that's just because that's what is convinient for me. it doesn't really matter when you brumate them, or when you wake them up. you can wake them up in the middle of winter as long as you have the correct heating and lighting (although I don't really wrry about lighting).
After that 2 months I just turned the heat back on. A week after that I gave them their first meal, which was half the size they normally tak. After they successfully took that I just went back to a normal schedual and tempature.
My male, although I did not personally brumate him, i just got him right as he was waking up, took food right after brumation, just as Aurora, the female I brumated did.
Hope that helps.
