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

[George]

Thanks Guys,

Sure I had planned to upgrade to above 5.2 , are these firmwares
available for download?

So the next question is really about the configs, Once a reboot is done
all the previous setting take in effect, is that so? And for a rollback
the do I just scroll for the image?

Regards
George
