Ive been tasked with writing the SOP along with implementing the above task of upgrading our core/aggregation and ISP routers in my environment.

We're currently running 11.4R7 and after speaking with our Juniper rep he has advised 13.3R9 would be the best choice.

I have gathered the necessary firmware along with whitepapers and procedures. This will be my first go round with a Juniper upgrade so I am as expected slightly nervous. Im fairly new to Juniper but have years of experience in Cisco environments.

Those of you who have experience in this, what can I expect as far as turn over time per device? Any gotchas you have seen or experience that are worth sharing? Ive read the upgrade guide all 350 pages along with many other things.

Those of you who have done this before what was your methodology for proceeding through the process start to finish?

Thanks in advance,
