I would like to change from using mboxlist_db: berkeley to mboxlist_db: skiplist I am reasonably confident that I should close down cyrus. Then, as the cyrus user, run ctl_mboxlist -d > /tmp/mboxlist.txt then rename /CONFDIR/mailboxes.db to mailboxes.berkely, then edit /etc/imapd.conf to change mboxlist_db to skiplist, then, as the cyrus user, run ctl_mboxlist -u < /tmp/mboxlist.txt to generate the skiplist vesion of /CONFDIR/mailboxes.db However, I am not sure about a couple of other things: Presumably I should rename /CONFDIR/db.backup1 and /CONFDIR/db.backup2 so that there is a clean start with skiplist? What about /CONFDIR/db and the files in there? What are they for? I need to be VERY VERY cautious about this change because of the dire consequences to our service if things go wrong! Advice will be most welcome.
