Catalysis of the transfer of a hexosyl group from one compound (donor) to another (acceptor). Catalysis of the transfer of a galactosyl group to an acceptor molecule, typically another carbohydrate or a lipid. Catalysis of the reaction: sucrose + 1-alpha-D-galactosyl-myo-inositol = raffinose + myo-inositol.
