You may want - stop cyrus - convert db files using cvt_cyrusdb - channge settings in imapd.conf to match the converted db files - start cyrus Note: current version of Cyrus will convert db files on the fly on nstartup, but your version doesn't do so. > > When I do add the skiplist stuff to imapd.conf, will it create new > skiplist files, so the old skiplist .db files can then be deleted? What They will be recreated, with the same name as they are now. Note: for deliver.db and tls_sessions.db, you could just delete the files instead of converting them, Cyrus will just recreate them and nothing really bad will happen if they are fresh files. It's really recommended to create a backup of the whole configdir before doing any changes. Simon > will they be called and will they be located in the same place?
