Did you checked / compared file sizes in the mailboxes - i.e. of single mails
and cyrus.* files? Possibly this is file system related (i.e. max number of
inodes or block size etc.) under the FeeBSD system (which filesystem do you
use)?
imapsync works well, if i.e. authenticated by a cyrus admin user (for all
accounts) in a single transfer. if you faced to problems with timestamps of
emails in mailclients, you may hace to use "--addheader" to regeneate the
timestamps from the mails during tansfer.
But before you start to migrate mailbox contents you have to migrate the
cyrus databases - i.e. mailboxlist, quotas.db etc.) - this usually means
exporting / importing mailboxlist, quotas etc. from the regarding database
files from cyrus.
see i.e.:
https://www.cyrusimap.org/docs/cyrus-imapd/2.4.7/internal/database-formats.php
rsync is difficult as the cyus.* files in the mailboxes may be binary or API
incompatible and the cyus partitioning / storage directoy layout has to be
the same on the new system. Even filesystem diferences aspects could make
trouble.
If you have sieve, you have to sync the sieve pool by i.e. rsync, but have to
make shure the diectoy layout is the same and "refresh" the sieve pool then.

Thee is no "quota" as default in cyus. You have to migrate your quotas
(quotas.db) before you start to sync mailbox contents.
hth a bit,
good luck,
Niels.
