Migration is a recurring movement behaviour or pattern, coconuts don't do that. You are probably thinking of dispersal, which is movement that results in gene flow, e.g. into a new place, permanently. That certainly occurs but it seems likely it isn't all that common, coconuts really only needed to disperse as far as the next coral atoll or island, which tends to be as far as a planktonic coral larvae can disperse. Really remote islands probably had coconuts introduced relatively recently by early settlers. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3936586/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3936586/
