dovecot - Feb 2012 - Migration to mdbox from Maildir, missing folders!

So I went and migrated a mailbox from mdbox from maildir format.

All seemed ok, but I've found that I now have some missing folders.

The mailbox in maildir format had some folders which contained an
'&'
sign, these appear to have been omitted...

What can be done? (I have a backup of the maildir box).

Note though that mdbox is now a live mailbox and has sent and received 
mails since the migration...

What Dovecot version? And give some specifics, like outputs of:

ls -a ~/Maildir/
ls ~/mdbox/mailboxes/

or something similar.
