Optimal solution (if available):
change address on old disk, set jumper to "read-only"
install new disk
install FreeBSD on new disk
mount old disk "read-only"
copy as desired
Seriously: you can* source upgrade across major versions - been
there - but every iteration is another possible failure mode.
You'll also be stuck with all the crud left over from previous versions.
