While the MIAA has turned a blind eye to certain over age kids, one being a freshman at UNC this year, they have always been pretty strict on their transfer rules. There are waivers if you move more than a certain miles(I believe it's 25 or 50). And if you didn't play Varsity at the previous school you don't have to sit. I know of several kids that played Club for a year because of the transfer rules.
