I like the idea of something like Notion but I have no idea how I would preserve my data or ever migrate it. I imagine you have to have some pretty complex stuff going on to have rich text, images, databases, macros and whatever else all in a file or notebook. Getting it out in some sort of format may not be too hard, but how would you ever migrate that to new software?

Am I over thinking this?

I know Obsidian stores everything in plaintext, but how would something like Notion or Affine (a self-hosted one) compare.
