I started out on Geni. After I explained my goal, an advisor suggested that I move to MyHeritage. Good advice! With some additional research, I was able to unite three trees that remained disconnected for two decades, after identified and assembled. It was easy to move data from Geni to MyHeritage via GEDCOM. However I learned that you burned the bridge for the other way around, i.e. via GEDCOM from MyHeritage to Geni.
I understand that automated importing from MyHeritage into Geni could cause a large number of duplicates, especially because of a mismatching maiden/married surnames file structure between them. My suggestion is to allow it to be done manually.
What I mean is to allow selecting one person on Geni, and searching for that person on MyHeritage. If a match is confirmed, Geni would offer matching that person's immediate relatives (only those covered by the "spider" that comes up clicking on "+") with people in those positions found on MyHeritage, and either adding them entirely if unmatched, or importing additional data from them.
Since this is normally done with external databases (news, vital records, etc.), it shouldn't be impossible to do it under the same roof now.
I intend to move back to Geni, and pull all the data I gathered on MyHeritage. For now, I am doing it 100% manually, having both open on my browser. There should be a more intelligent way of doing it, clicking instead of typing.
