From the MyHeritage Blog 1 December 2018:
We have just extended our deadline for free DNA uploads to December 16, 2018. As of this date, our policy regarding DNA uploads will change. DNA Matching will remain free for uploaded DNA data, but unlocking additional DNA features will require an extra payment for DNA results uploaded after this date.
You will need to have downloaded your raw DNA data from the original testing site. The MyHeritage Blog has a link to lead you through the upload process. I’ve uploaded my DNA data from my test to this site.
Uploading to multiple sites is a way to potentially reach more DNA cousins and make more research connections. Of course not all people respond. You will have access to all currently available features of the DNA section of the MyHeritage site, including the chromosome browser. That information can then be used to “paint” your DNA at sites like www.dnapainter.com.
