Hello Salento. I agree with you. The best alternative is to purchase a new kit for testing with the new chip. All the "big" ones in the market updated their chips in 2019.
This was the case of Gene by Gene (FTDNA) and MyHeritage, for example. Since the beginning of March 2019 MyHeritage DNA done an upgrade to a new and more advanced DNA chip.
The chips that now is used for reading DNA samples in their lab and converting them to digital data are developed by Illumina, a company considered to be the “Intel” of DNA processing. These chips are produced with very sophisticated technology. They are not electronic chips but are made of glass slides harboring millions of tiny beads. Each bead is coated with synthetically generated DNA strands of about 50 nucleotides each that serve as probes. When the DNA of a customer is placed on a chip, it binds with the probes and generates an optical signal that is read by laser using lab devices produced by Illumina. This is a simplistic description of what goes on behind the scenes at the lab. See the video below:
Until recently, MyHeritage DNA tests were processed using Illumina’s Omni chip. To provide their customers with a more robust and powerful analysis, they decided to upgrade to a new and more advanced custom-designed version, based on Illumina’s Global Screening Array (GSA) chip. The process of designing the content of the new chip and working with Illumina for them to manufacture it for them took more than a year.
My results displayed in 28th july, 2019 already were processed using Illumina’s Global Screening Array (GSA) chip. Because of this I believe that the raw data I uploaded to LivingDNA is more accurate and, at least for me, LivDNA results must be considered precise, even beeing an upload of data raw of another company.
Cheers
