      dtvmcdonald remarked: "I checked and there are about 211,000 actually useful SNPs in common between old old and new FTDNA chips."

      BroderTuck observed that "It is true that the new GSA chip tests a very different set of SNPs compared to the old Omniexpress one, but
      1) More or less all testing companies are now using the GSA chip, and the percentage of people tested with the new chip will continue to grow.
      2) FTDNA has done something that (as far as I know) none of the other testing companies have done, namely using the 50K customizable SNPs on the GSA chip to fill in as many gaps as possible to improve compatibility between chips."

        So, does anyone know if we have to re-test on the new chip?
