The concat device should just appear automatically after the upgrade as long as you (continue to) load the geom_concat kernel module. Be aware that if the on-disk metadata format has changed then it will automatically be upgraded. This is usually a good thing but if you need to roll back to 6.x for some reason it's something to take into consideration. > Planned upgrade: > Reboot from cdrom, install FreeBSD7 from cd to ad0 Just curious, is there a reason you're going this route instead of upgrading from source?
