Best practices for migrating from Roam?

I’m going through the migration from Roam to Obsidian myself. For my “Daily Notes”, I’m trying to find a way to change the date creation of the file to match the actual name of the .md file to be able to sort all my old daily notes by date created. Any tips or tricks to this?

Side note: I’m a bit nervous & hoping my github export of markdown files contains everything lol.
