Each time I see posts like this, each time I see that it doesn't have a proper Android app with WebDAV sync and, disgruntled, go back to Joplin cause it lets me have my notes with me anywhere
I think I tried this out back in the day when searching for what I would use for PKMS! Don't remember why I didn't settle on it. I like FOSS stuff but the switching cost from Obsidian would be high—even if there was something to auto-move everything over I always like to manually move things so I can strike out unused things, improve existing notes, restructure my notes, etc. but maybe to support FOSS I should just find an auto-import if it exists and do it anyways.
Not sure if this would be considered off-topic for !obsidianmd@lemmy.world but you might want to crosspost there. I would welcome it. !FOSS@beehaw.org and !opensource@programming.dev would also like this.
You are perfectly welcome to cross-post this to other communities. I will pass it over to the last two but might leave Obsidian alone for now as it isn't specifically about it.
If you find an importer let us know. I haven't finished manually importing to Obsidian from OneNote (after previously importing from Evernote) but would be interested in giving this a try.
