Have you tried to explicitly create the the mailbox after the fact?

  cm user.xxx

This can be done nondestructively. I remember needing to do this for 
some mailboxes when I used imapsync to migrate from uw-imap. It's 
inconvenient, but if you're only talking about a fraction of 98 users, 
it might be feasible.

If you've already migrated your data, you might also consider adding 
some flags to reconstruct:

  /usr/sbin/cyrreconstruct -rf

My most recent migration was between two similar environments using the 
same version of Cyrus IMAPd (2.3.11). In that case, I simply copied all 
data to the new server, identified and removed the following Berkely DB 
files:

  /var/imap/deliver.db
  /var/imap/tls_sessions.db
  /var/imap/db/*

Then I started Cyrus, which rebuilt the missing databases. It worked 
like a charm, with no need for reconstruct or imapsync. However, I don't 
know if this is an option for the 2.2.x series.
