We show, using basic Morita equivalences between block algebras of finite groups, that the Conjecture of H. Sasaki from [H. Sasaki, Cohomology of block ideals of finite group algebras and stable elements,  Alg. Repres. Theory  16  (2013), 1039–1049] is true for a new class of blocks called nilpotent covered blocks. When this Conjecture is true, we define some transfer maps between cohomology of block algebras and analyze them through transfer maps between Hochschild cohomology algebras.
