I have argued that if life, intelligence, and consciousness are simply patterns then space travel might not require sending matter from place to place. (Trans. Kansas Acad. Sci., 118 (1-2) 2015, pg 145) Biologists point out, however, that we have not really sequenced 100% of the human genome just yet so much work remains to be done. (How to clone a mammoth, B. Shapiro, Princeton U. Press, 2015) The supporting biochemical environment/machinery is also important. Just how much information we would have to send would actually depend upon how different life is from one place to another in the universe.
I would think that interstellar travel would be easier for AIs/mechanical life.
