[j-nsp] MX80 upgrade caveats

[COOK, MYLES]

There were enough difference between 11.x and 12.x that you had to move to at least one version of 12.x before moving past.  Once you are on the 12.x code train jumps will be a little smoother.

If memory serves, our MX's shipped with 12, and we were able to jump
straight to 14.1.

I can't recall which version of 12 it was, though.
