Since last March, we have helped Windows users import 71 million Evernote pages to OneNote. Following the great feedback we received, we want to help even more people make the move. Today, we are launching the OneNote Importer tool for Mac. You may feel hesitant about moving all your notes from a place you know to a new online home. Don’t worry, the Importer tool makes moving day easy.
Hi Lana, I used this tool to migrate recently. It didn't work if I tried to use my Office 365 OneDrive account, as it claimed there were too many files in the drive. In the end I had to create a personal OneDrive account and use that to transfer. I do have a large number of books in Evernote, and files in OneDrive. So maybe I'm a unique case. If you'd like me to try again and grab specific screenshots/logs etc let me know.
