I can use the following commands to mount that ISO.
# vnconfig /dev/vn0c ./image.iso
# mount -t cd9660 /dev/vn0c /cdrom

I don't find the sysinstall on the CDROM ISO but do find /base/install.sh,
which attempts to pour the base system to the root /.

I am doing a test in VMWare before carrying out the *real* upgrade on my
- Install a minimal 4.7 system
- Mount the ISO as /cdrom
- Run the /cdrom/base/install.sh and got an updated root /
- Reboot the system (it now tells me that it's 5.0 :D)
- Run sysinstall again
- Follow the standard way to re-partition and re-format my hard disk with
This seems to be working in VMWare.
Are there any *bad* aspects or effects that it may bring to my system? I'm
just playing around FreeBSD now and have backed up all my .rc and /etc
files to my FAT32 partition before this surgeory. :)

My biggest concern on my approach above is whether it may leave some old
files on the disk. Please note I both selected Minimal during install.
