This are the steps I've done, when migrating from Centos 5 to SL6: - Backup mailboxes list database using "ctl_mboxlist -d >mailboxes.txt" - Copy /var/lib/imap and /var/spool/imap/user/ to the new system. - Removed deliver.db and tls_sessions.db. - Recovered mailboxes list db using "ctl_mboxlist -u <mailboxes.txt" > I suggest to switch to skiplist for all > databases. And make sure you clean up /var/lib/imap/db. BTW, deliver.db > and tls_sessions.db are not so important, you could configure skiplist and > just remove those dbs and also the content of /var/lib/imap/db. Is skiplist the preferred format? I currently use the defaults cyrus reccommends. I don't have any format parameters in my imapd.conf. How do I switch the two BDB databases to skiplist? I think "tlscache_db" is the parameter for tls_sessions. But which one is responsible for deliver.db? This is my imapd.conf: admins: cyrus root allowanonymouslogin: no allowusermoves: yes allowplaintext: yes autocreatequota: 200000 configdirectory: /var/lib/imap createonpost: no dracinterval: 0 drachost: localhost lmtp_overquota_perm_failure: no partition-default: /var/spool/imap poptimeout: 10 quotawarn: 85 reject8bit: no sasl_pwcheck_method: saslauthd serverinfo: min sieve_maxscriptsize: 64 sieve_maxscripts: 50 sievedir: /var/lib/imap/sieve sieveusehomedir: false timeout: 30 tls_cert_file: /etc/cyrus-imap-ssl-cert/server.crt tls_key_file: /etc/cyrus-imap-ssl-cert/server.key The IOERROS could (temporarily) repaired by removing cyrus.cache and cyrus.index (sometimes cyrus.header also) and doing a reconstruct. Also I have this *.NEW files in the mailbox folder when it's bringing this errors. Couldn't be a problem with this files or processes that access this files, too? Or could it result from the other (BDB) databases? Regards, Marc ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
