I am trying to rescue some old notes from Evernote and move them into OneNote. As an experiment, I exported a couple of thousand notes into enex files and then made use of the official OneNote importer:

https://www.onenote.com/import-evernote-to-onenote

But I was distressed to discover that this software is apparently no longer functional. (Some years ago it worked fine for me.) I next, just as a test, tried to import the enex files into UpNote, and that was more or less successful. (Only a few notes containing large image files failed to come through.)

At that point, I started moving files manually by copy-and-paste into OneNote, but I eventually concluded that it would take me several months to do this. Has anyone else here found a better solution? My UpNote experiment suggests that there is nothing wrong with the enex files and that the problem must be in OneNote's import software.

It would help to know the OS you are using. If you're using Windows I found these troubleshooting steps for the importer:

There's also this open source evernote2onenote importer, but it hasn't been updated in 5 years so I don't know how well it works:

Otherwise I'd consider importing into an intermediary competing notes app is a possible alternative. For example, importing into NoteJoy https://notejoy.com/help/import-evernote ), then exporting all notes to Google Drive as Google Docs (a feature built into Notejoy), which can then be imported into Onenote ( https://notejoy.com/help/export-notes ).

Alternately you could use Zapier or IFTTT to migrate all Evernote notes to Dropbox or Google Drive, and migrate the files from there.

If the macOS Onenote importer didn't work I'd import the Evernote account into Apple Notes ( https://support.apple.com/en-us/HT205793 ), then re-export it to OneNote. The 3rd party Exporter app unlocks for $4.99 and exports Apple Notes as HTML or Markdown but apparently doesn't handle images https://apple.co/3pIxuGr

Actually, in all these cases I think you might need to migrate images manually. Also, in all cases you lose all internal links between notes created in Evernote.

Thanks, satis. I'll look into these possible solutions.

I've also noticed advertisements on the Web for Gem OneNote Batch:

I wonder if anyone here has tried to use it?

Sorry if I failed to mention earlier I am using OneNote 2016 on a Windows computer.

FYI I just ran across this blog post

https://eclecticpassions.net/blog/quick-guide-export-notes-from-evernote-to-obsidian/

which noted that the Obsidian Importer plugin

https://obsidian.md/blog/free-your-notes/

converts Evernote .enex files to .md, putting images into a separate Resources folder.
