I'll give a +1 recommendation for upgrading any kit at FTDNA with older results to BigY-700, as long as there exists the possibility of getting a fresh sample if required.? BigY-700 is the most affordable penultimate Y-chromosome test that exists now, and for the foreseeable future.? The Ultimate test being a "T2T" sequence, but that is a test that is much too expensive at this point, and we're not even sure just exactly how expensive it would be, if it even could be made available.

(Well, I did buy a few tests from them, but all I got back was satisfaction.)
