Well, in theory PM is about the processes and you need not know about the underlying content... I used to be a non-IT PM but never tried to make the transition. On the other hand I worked with PMs who had variously done aerospace, automotive, construction, utilities, banking, IT, etc etc and they had all managed to make it transferrable so I guess it's not out of the question. Hit them with a vit of PRINCE and a bit of V-Model...Good luck!
