Qualification Conversions

C++You can convert an rvalue of type cv1 T* where cv1 is any combination of zero or more const or volatile qualifications, to an rvalue of type cv2 T* if cv2 T* is more const or volatile qualified than cv1 T*.

You can convert an rvalue of type pointer to member of a class X of cv1 T, to an rvalue of type pointer to member of a class X of cv2 T if cv2 T is more const or volatile qualified than cv1 T.
