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?
