Before this gets off into an Tetrix/FTC vs VEX/VRC debate...

Just remember that VEX was originally developed for FRC teams to use in prototyping, way way back in the day (OK, so it hasn't quite been a decade yet). VEX is cheaper; the strength is at least comparable between the two (unless you're talking about motors that are (mis)used in FRC); both have curriculum. Competitions could be a factor; some areas seem to have better VRC coverage, while others seem to have better FTC coverage.

With those things considered, it's the choice of the educator which curriculum is chosen.

With respect to the original question, they should transfer just fine. It's just a bit bigger of a machine...
