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?

differences in how to manage the server? How effective is the mb2md? Not looking
for a cookbook, just an opinion on whether it is worth converting.
