[j-nsp] Automation of EX code upgrade

[Mick Burns]

Hey all,

I am looking for ideas/previous experience in the best way to automate the
upgrade of multiple (let's say about a hundred units) EX switches in large
datacenters.  Let's assume here they are a mix of 3200 and 4200 and all of
them runs the same JunOS release.  Any failure must be quickly identified
for a manual upgrade.

Any help or advice is much appreciated.
