It's also perhaps worth mentioning that Postfix has nothing to to with
mail once it has been delivered. This question should have been sent
to a mailing list for the unstated IMAP server.
This is almost true. The main caveat is that either the old or new Postfix
is up and running, it is not safe to copy mbox files, as mail may be lost,
and messages at the tail of the file may be corrupted.
Transfer of mailboxes must take place between idle systems where Postfix is
not running on either end.
Otherwise, indeed the mbox file format hasn't changed in decades.
Thanks to all who have responded. I'll be performing the cutover
later this weekend.
