I wanted to get rid of OneNote. There was no real evolution over the years and with Markdown based Notes, I can use them in the future everywhere. Well the long term goal is to get rid of Microsoft, but that’s a whole different story. So, I changed to Joplin.
I used the OneNote MD Exporter. It’s not perfect but at the time of writing still better than the native Importer from Joplin. By the way: If you want to export your OneNote Notebooks as a Zip for the native Import, you need to change the OneNote Website to English, or the export page is just white and broken.
Some to-do lists looked bad. Big images (e.g. from the phone) where not exported.
I opened both side by side, changed the order to alphabetical and look through them. Most work was copy/paste the very large images and Joplin ask you to resize them to 1920 px and that’s totally fine in my case.
Addons
As for Addons, I installed these three:

Save Folder
I like to have my files in Documents, not somewhere inside AppData.
You need to move the files to another place an then create a new shortcut with the –profile option:
C:\Users\username\AppData\Local\Programs\Joplin\Joplin.exe --profile "C:\Users\username\Documents\whereveryoulike\joplin-desktop"
