Doing a ctl_mboxlist -u is very I/O intensive, so, if you have the ability to use a memory based filesystem do do the conversion on then use it. On Solaris our /tmp is such a FS, so we used ctl_mboxlist -u -f /tmp/mailboxes.db < /tmp/mailboxes.tmp to do the conversion and it took around 10 minutes, doing it on a "normal" FS looked like it was going to take 2-3 hours. We have around 34,800 entries in our mailboxes.db file.
Needless to say, you must do this with cyrus down... -chris On Monday, February 4, 2002, at 12:01 PM, Connie S.
