Migrating the cyrus-imapd backing store to a new server, while at the same time changing the mailboxes domain, can be a bit tricky. The following procedure works for me.
These notes are for Kolab’s version of cyrus-imapd (2.5~dev2015021301-0~kolab1.1).
Stop all the services on the target machine that might interfere with the migration.

service wallace stop service postfix stop service kolab-server stop service kolab-saslauthd stop |
Make a backup of the target machine’s LDAP database. Delete the target DN ou=People,dc=(the mail domain), it will be restored in a later step.
For a new migration stop the target cyrus-imapd service and clean the directory structure.

cd /var/lib/imap service cyrus-imapd stop rm [a-z]*db rm -rf db/* # Kolab may already have setup the proper quotas # rm -rf domain/* rm -rf /var/spool/imap/domain/* rm -rf /var/lib/imap/lock/* # cp -rp /root/migrate-cyrus-imapd/vsi-work/domain /var/spool/imap service cyrus-imapd start service kolab-saslauthd start service kolab-server start service postfix start service wallace start |
Restore the DN ou=People,cn=(your domain) that you deleted above. Kolab will notice the change in the LDAP directory and recreate the mailbox structure in the cyrus-imapd spool files.
Now synchronize the backinstore with imapsync.
Imapsync might have a problem finding the mailbox folders. Notice the difference specifying a domain can make.
