[j-nsp] M320 SW upgrade from Junos 8.4 to 9.2

[Robert Kern]

Hi,

We know that there is a big change from 8.4-8.5, that is why we decided to
wait a for a while.
Now we are planning to go with 9.2. We have enough free space to do an
upgrade. The question is how should we do an upgrade or what are your
experiences? Should we go directly to 9.2 ar we should do a step-by-step
upgrade --->8.5--->9.2?

Thanks,

Robert
