[j-nsp] Old JunOS upgrade path

[Ola Thoresen]

Not that I am in any way authoritative... And I think  Juniper has 
official guidelines, but these might be a bit conservative. Depending on 
your config and feature sets.

But I would at least suggest doing a few steps.

13.2 to 15.1 should be ok - skipping 14.

15.1 to 17.1 (and probably even 17.4) should also be ok, skipping 16.

But do a backup, and verify in each step. The biggest changes are from < 
15 to 15+
