Yesterday on the Ancestry Insider blog there was more information about the migration of sources from New Family Search to Family Tree. This is another perspective on what the The Ancestor Files blog reported about this. Apparently the sources data is "corrupted" because there are ten fields for sources in New Family Search and three fields in Family Tree. Also, the sources are being placed in user source boxes. I will have to check my source box and see if there is any thing there that I need to attach to my people in Family Tree.
I was encouraged to read that this is a new round of migration which started in February and was expected to last about six weeks. So maybe it is almost over now. Regardless of what FamilySearch is doing it is incumbent upon me to add sources to my people in Family Tree and to have good citations for these sources.
