This all did not work for me. At last it worked for me with the following steps as root:
1. Backing up /var/lib/cyrus 2. Changing /usr/lib/cyrus/cyrus-db-types.txt DBENGINE BerkeleyDB => DBENGINE BerkeleyDB4.7 3. /etc/init.d/cyrus-imapd stop 4. rm -rf /var/lib/cyrus 5. apt-get upgrade 6. Restoring /var/lib/cyrus 7. db_dump deliver.db > deliver.dump 8. db_load -f deliver.dump test.db 9. cp test.db deliver.db 10. rm test.db 11. db_dump tls_sessions.db > tls_sessions.dump 12. db_load -f tls_sessions.dump test.db 13. rm test.db 14. /etc/init.d/cyrus-imapd start
Maybe this is helpful for someone else. Thanks to all others in this thread leading me to a working solution.
