Let X be a random variable with distribution function F.  Take a transformation on X, say Y = T(X),  given that mth moment of Y and mth moment of X are different.  Then, does it implies that remaining (m-1) moments are also different from X's (m-1) moments?   Do we need to have some additional conditions on T ?

i.e.,  after transformation,  preserving mth moment does it implies that remaining (m-1) moments are also preserved ?
