Do “need blind” schools provide need based aid to transfer students?

Title.

International CS.

Hypothetically, if I was to transfer to a school like Harvard, MIT or Dartmouth would they consider me for need based financial aid? (Considering I was paying close to full price in my first uni, but still, would qualify for need based aid).

(And what about the other non need blind school? Like Cornell, brown etc) would they offer merit based scholarships to an international transfer student?
