Split mailboxes on server migration

I come to bring you some good news.
Actually the problems I was facing had nothing to do with database stuff
at all. It was a single configuration line (DEFAULTDOMAIN) in IMAPD.CONF
that was set to DOMAIN.EXAMPLE while it was set to IMAP.DOMAIN.EXAMPLE
in the old server configuration file.
Earlier, before figuring out what was the issue, I noticed that using
the wrong domain made Cyrus look for the mailboxes in
DEFAULTPARTITION/U/USER instead of looking in
DEFAULTPARTITION/DOMAIN/D/DOMAIN.EXAMPLE/U/USER. And thus, when creating
manually mailboxes, they were being created out of that domain
While this solved my problem, it brought me some really bad confusion.
I looked for an explanation in the Cyrus imapd.conf docs, but nothing
that related one thing to each other was found.
Anyone could shed some light on this? I just can't let this pass with no
Thanks in advance!

These servers are running the newest version of Cyrus-IMAP available to a Debian system (2.5.10-3), while the old server runs Cyrus on version 2.2.13-14. I've done the migration of another server running this same version to the newest version with no problems.
