What is the best process to transfer a massive amount of emails/mailboxes from High Sierra (10.13.3) Apple Mail to Catalina?
I've read migration assistant is horrible, "export mailboxes" doesn't work, and that transferring the v5 folder to the v7 may work (but no confirmation).
If I transfer v5 to v7, do I move the contents from one to the other? Or do I just copy over v5 and see what Mail does with it?

The most trouble free way to move to a new machine, is using the Setup Assistant on the initial boot— you have one shot here. https://support.apple.com/en-us/HT205749
If that opportunity has past, the second best way is use the Migration Assistant.

So I copied all the files over, propagated permissions, deleted the plist file, renamed the v5 folder as v7, and opened mail. I got a message saying "upgrading library" and then Mail opened an only showed my icloud account and nothing else, and proceeded to freshly download all 64k emails.
So copying the v5 folder doesn't work, FYI to anyone else who is trying this.
