We consider two different versions of gauged WZW theories with the exceptional groups and gauged with any of theirs null subgroups. By constructing suitable automorphism, we establish the equivalence of these two theories. On the other hand our automorphism, realtes the two dual irreducible Riemannian globally symmetric space with different characters based on the corresponding exceptional Lie groups.
