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

[David Ball]

   We went from 8.5->9.1R1.8, then to 9.2R2.15, both with little or no
problems.  I don't know of any specific reasons to not go 8.5->9.2,
but Release Notes and upgrade instructions may provide insight.
Otherwise, 8.5->9.1->9.2 worked for me.
