Transfer EMAX from old contract to new

I bought emax under the old contract (mishap) and have it save on my MetaMask app. After learning I need to purchase it under the new contract # I tried to swap it under the new contract and the MetaMask won’t support the old emax. Now I have tokens under the old and new emax contract. MetaMask nor uniswap will allow me to trade emax. What am I supposed to do?
