How to migrate second time to Photos
I accidentally migrated to Photos. I know I can keep using iPhoto which appears to be fine. But if I make changes in iPhoto, how can I make a second migration to Photos at a later date when ultimately I want to convert permanently and overwrite my initial mistaken migration? I have made no edits in Photos.
Thanks, Ralph
