Moving On My Mac emails to new computer without Migration Assistant

I want to move my apple Mail to a different computer of mine that is already setup. I am primarily concerned about maintaining the file organization of emails that are locally organized as "On My Mac". Can I manually move my V10 folder on my current computer [in Application Support>Mail] to the newer computer that I would like to use? I don't want to use Migration Assistant because everything for that user is already set up well. I can then set up IMAP accounts again manually. If I export the On My Mac mailboxes manually instead as a MBOX, and import them at the new computer, they end up in a disorganized imported inbox.

Thanks. Happy 2026!
