Hi, I'm planning and testing the migration of a IMAP mail server based on cyrus 2.3.8 with about 3TB of mailstore, 300 users and a lot of shared folders (with shared flags (group permission with +w)). The old server is a 32bit one and the new one is 64bit virutual machine. as now I've succesfully used this procedure: - Rsync of all mailstores /var/lib/imap and /var/lib/sieve - rm -v /var/lib/imap/db/* /var/lib/imap/db.backup1/* \ /var/lib/imap/db.backup2/* /var/lib/imap/deliver.db \ /var/lib/imap/tls_sessions.db /var/lib/imap/mailboxes.db - ctl_mboxlist -u < /tmp/mboxlist.txt - ctl_cyrusdb -r - tls_prune - ctl_cyrusdb -c - cyr_expire -E 3 The last command took about 24 hours to complete and if understand right It converted cyrus mailbox DBs from v9 to v12. I wonder if the first cyr_expire could run even with the service started and if it should be better to run a reconstruct on all the mailboxes in place of this cyr_expire. Last but not least, do you think that sieve filters should be recompiled? Any other hints?
