Bad time to repot a phal?

[irrka]

I've had this big phal from Ikea for over a year now. It was flowering great when i first bought it, and hasn't flowered or spiked since. The old spike is still on and the leaves look fine. It's in sphagnum and i read that you're supposed to re-pot sphagnum after about a year, but then people say to wait until it's done flowering. Since i'm not seeing any new growth, should i just try moving it now or wait until spring "to be safe" that nothing new is going to happen?
