You can't convert flying club to elevate or the other way around, as far as I know. The two airlines are partners, so you can use elevate points for redemptions on VS, and use Flying Club points for VX redemptions. Same goes for earning points (flying paid VS can earn you Elevate points, for example) Both sites have their various award redemption and earning charts on their websites. But no, the points themselves are not at all interchangeable or transferable in that way (and flying club points are worth far less than elevate points, generally)
