[j-nsp] How to upgrade junos 5.0.0r8.1

[Tim Eberhard]

You configuration will remain after the upgrade/reboot.

Downgrading is the same process as upgrading as long as you're going from
say 5.2 to 5.0. Just load the 5.0 image and reboot. The 5.0 image is blown
away when you load the newer screenOS.

Good luck,
-Tim Eberhard
