Agreed I am looking to migrate in place, if I migrate at all. I'm still
researching the benefits (aside from mail-encrypt) to using Maildir instead. It
may be the new default, but to me it is an unknown.
I am going to play with the mb2md utility
(https://centos.pkgs.org/7/epel-x86_64/mb2md-3.20-17.el7.noarch.rpm.html) in a
test instance to see if migrating in place is a feasible.
Thanks for your responses, very much appreciated.

Unfortunately, this document doesn't really address the OP's need,
which is to migrate mailbox formats on the same server. Now migrating
to a new server would work, where the new server was setup to use
maildir as the default.
Maybe a new section could be added talking about this situation in
more explicit terms, with some real examples of conversions?
