Split mailboxes on server migration

Calling just RECONSTRUCT -F with no parameters, gives me output for all
imported mailboxes, but still no sign of the mailboxes being created.
And again, if I try to create the mailboxes manually, no usage is
accounted for the mailboxes.

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.
