If you decide to upgrade I would advise you to do the make world method. Its older and therefore more tested, and as you have said you are more familiar with it. I have done about 40+ upgrades from 6.x to 8.x. I did a step to 7 in the middle, and all worked fine. The only oddity I found was that when I went from 7.x to 8.x dangerously dedicated disks devices were presented differently. In 7.x you had ad0a, ad0b etc under /dev, but you also had ad0s1a, ad0s1b etc as well In 8.x you only had ones of the format ad0a. the oddity was the ad0s1a format ones being present prior to 8 being present, as I wouldn't have expected these. This was only and issue as whoever had built to box i inherited had used the ad0s1a format ones so on rebooting to 8.x we had issues. A quick edit of fstab fixed the issue though. Also make sure you have mergemaster configured proply as it will take a load of work out of the upgrades. Here is my rc for it. You may need to tune it a little cat /etc/mergemaster.rc AUTO_INSTALL=YES AUTO_UPGRADE=YES PRESERVE_FILES=yes PRESERVE_FILES_DIR=/var/mergemaster/preserved-files-`date +%y%m%d-%H%M%S` IGNORE_FILES="/etc/crontab /etc/fstab /etc/group /etc/hosts /etc/inetd.conf /etc/make.conf /etc/master.passwd /etc/motd /etc/newsyslog.conf /etc/ntp.conf /etc/ntp.drift /etc/profile /etc/rc.conf /etc/resolv.conf /etc/services /etc/shells /etc/syslog.conf /etc/ssh/sshd_config /etc/ssh/ssh_host_key /etc/ssh/ssh_host_key.pub /etc/ssh/ssh_host_rsa_key /etc/ssh/ssh_host_rsa_key.pub /etc/passwd /etc/rc.conf.local /etc/zfs/exports /etc//namedb/named.conf /etc/periodic.conf /etc/hosts.allow /etc/hosts /etc/pf.conf /etc/sysctl.conf /etc/make.conf /etc/src.conf /etc/mail/aliases /etc/mail/mailer.conf /etc/remote"
