Merging family trees that match mine

There are five ways to merge profiles - https://help.geni.com/hc/en-us/articles/229705547-How-do-I-merge-du...
Drag and drop (from tree view) and merge this profile (from profile view) are probably what you want. Both work fine whether or not you are a Pro.

I have managed to merge the trees on my profile on My Heritage but cannot merge my profile from My Heritage to my profile on Geni.
Can you please help me with doing this. Every time i press to view the profile, I get taken to the page for signing up for subscriptions.

I would like to have both profiles that I manage to agree so that those who are on Geni can also merge with my tree.

You cannot merge MyHeritage Profiles and Geni Profiles.
It cannot be done.
MyHeritage owns Geni, but they are run as totally separate.

I managed to do the merge by exporting GEDCOM from My Heritage and importing GEDCOM into my tree on Geni. It did result in a couple of duplicates which I managed to merge and delete but now my tree on Geni has grown enough for me to contact the collaborators to connect me with the other family members that now have matches.

Thanks for trying to help me.

Now you can try it too.

To me, merging means combining to make one.
The way I understand the term, you have not merged them -- changes to one will not automatically result in changes to the other. They are still separate.

If you had asked how to update your profiles on Geni with the info on MyHeritage, l would have recommended SmartCopy. - https://www.geni.com/projects/SmartCopy/18783

Doing a Gedcom Import is likely to be a bad way to update profiles on Geni -
it will likely create lots of duplicates
And when duplicates are merged, the old version may be Primary, in which case the new values may not show - so you have to click Actions and see if there is a line for Resolve Data Conflicts, and if there is, click it and see if you know which is correct, and if so, choose it (if not, leave the Data Conflict - do not choose if you do not know, unless it is just a matter of taste, like MA vs Mass. vs Massachusetts)

SmartCopy gives the choice of creating Profiles, or of updating where they already exist.
I was focusing on those that already exist, but realized it might not be clear it is also for creating new profiles on Geni.

Since the Tree on Geni and the Tree on MyHeritage are still separate, if you ever decide in future you want to update Geni again from your MyHeritage Tree, please use SmartCopy and do not do another Gedcom Import.
But glad that worked out for you this time.
