Joplin’s notes can easily be exported as standard markdown (File | Export All | Markdown).
When I was evaluating Joplin and Obsidian for my notes, I switched between them multiple times and it was very easy. The folder of markdown files exported from joplin can be opened directly as an obsidian vault. The only issue is if you had resized any images with Joplin’s rich text editor (doing that converts the images to html img src tags, but that was easily fixed with a script to convert them back to markdown links)
