So for your information:
the Output of "ctl_mboxlist -d" contains
the mailbox name, if it is a local or remote mailbox, the partition  
(or server and partition for a remot mailbox), and acls for each user  
that has acls on that mailbox.

user (for users owned mailboxes) and DELETED (for delayed deletion of  
mailboxes "delete_mode: delayed" in man imapd.conf ) are special  
prefixes,
all other mailboxes are shared folders.

The hash in the DELEDTED mailboxname is the times that the mailbox was  
deleted (unixtime in hex)
to allow multiple mailboxes with the same name to be deleted.

See "expunge_mode: delayed" in man imapd.conf

Are the old mails (from before the upgrade) in the same location?
