I have a friend who is asking if they can download the information from Root's magic into Family Search. If so, what are the steps to do this?
You sort of can, but please, just don't. Most of the people in your friend's RootsMagic file probably already have profiles here, and a mass upload would just create a mess of duplication for people to clean up.
See Gordon's comments and video: https://community.familysearch.org/en/discussion/153520/add-imported-gedcom-file-to-existing-tree#latest.
RootsMagic syncs with FamilySearch Family Tree. Please reach out to RootsMagic for instructions on how to sync each person one-by-one in your RootsMagic database with FamilySearch.
Thank you. I will pass the word along.
