James,
Patrick is entirely correct.  As explained in the man page for ctl_mboxlist(8) the "-f" flag is to specify an alternative input file (mailbox database) not an output file.  Output is via standard out, and can redirected into the file of your choice, or piped to the new host, like so:
$ sudo -u cyrus /usr/lib/cyrus-imapd/ctl_mboxlist -d | ssh -tt newhost.example.com sudo ctl_mboxlist -u
Assuming you have the configuration directory specified in imapd.conf(5) on both systems, the right DB files should be used.

Cheers,
    -nic

is consuming any cpu.

If I press <cr> I see this:

line 1: no partition found

line 2: no partition found

line 3: no partition found

. . .


There is only one partition on both systems and it is
'/var/spool/imap' on both.

I have also tried the method suggested on the 3.0.6 documentation
respecting upgrading and use rsync to move over mailboxes.db.  In each
case I cannot get reconstruct to run and upgrade or rebuild the mail
store on the new service.

# sudo -u cyrus /usr/local/cyrus/sbin/reconstruct -r -f -V *
#

I get an immediate empty return.

I know that there exist physical mailboxes on the server that cyradm
does not report.  I know that these mailboxes exist on the old server
and therefore I infer are present in mailboxess.db.

How do I get the contents of the old mailboxes.db file into the new so
that reconstruct will run?




Pretty sure you are using -f incorrectly. Try this:

sudo -u cyrus /usr/lib/cyrus-imapd/ctl_mboxlist -d > /var/spool/imap/mailboxes.db.txt

 on the old followed by a transfer of /var/spool/imap/mailboxes.db.txt

 to the new followed by:

sudo -u cyrus /usr/local/cyrus/sbin/ctl_mboxlist -u < /var/spool/imap/mailboxes.db.txt

on the new
