Postfix Cyrus Web cyradm HOWTO

Update is critical and can mean

complete data loss

Please test this procedure on a test/pre production server first.

Also have close look to

install upgrade.html

that comes

with the cyrus imapd distribution. Please note, that you shoud

plan a downtime for the production server to have the time to

solve problems. Also note, that nobody I cannot take

responsibility for the update procedure provided here

Cyrus changed the format of the dbd databases used for internal storage of

mailboxlist flags etc.

A convert script comes with the distribution. The most important database is

/var/imap/mailboxes.db

. Without that database cyrus imapd will NOT run.

This requires a backup. Lets do a dump and a backup of the database.

/etc/init.d/cyrus stop # be sure no cyrus process is running

lsof /var/imap/mailboxes.db # be sure NO process is accessing the mailbox file

su   cyrus

/usr/cyrus/bin/ctl_mboxlist  d > /tmp/mailbox.db.dump

cp /var/imap/mailboxes.db /var/imap/mailboxes.db.old

Convert the

/var/imap/mailboxes.db

/usr/cyrus/bin/cvt_cyrusdb /var/imap/mailboxes.db berkeley /var/imap/mailboxes.db.new skiplist

mv /var/imap/mailboxes.db.new /var/imap/mailboxes.db

Convert all the  seen  databases:

find /var/imap/user  name \*.seen  exec /usr/cyrus/bin/cvt_cyrusdb \{\} flat \{\}.new skiplist \;  exec mv \{\}.new \{\} \;

Converting the sieve scripts

/usr/local/cyrus imapd 2.2.3/tools/masssievec /usr/cyrus/bin/sievec
