Both FTDNA and MyHeritage started out using the Illumina OmniExpress and changed over to the Illumina Global Screening Array in about 2018.
?
There is very low overlap therefore between old and new tests done at both MyHeritage and FTDNA with only about 150,000 out of 700,000 SNPs in common between the two chips. See:

FTDNA now only accept MyHeritage transfers for tests done after 1st March 2019.

In general one needn¡¯t worry about FTDNA/MH transfers as FTDNA processed all of them and the SNP overlap is very high.
Some people like their MH ethnic origins %, but many people would place them at the very bottom. ? These estimates are several years old and very outdated.

For several years, FTDNA processed Nat G¨¦o Geno kits. ? I know there were several iterations, with the last by Helix.
Are any of the FTDNA versions being considered for Y updating of Nat Geo transfers to Family Finder?
