Solved: Cisco ISR4331 Upgrade path

JMcLaren · ‎03-05-2018

Hi all,

We are presently using 3.16.S6. It is being suggested that we upgrade to Denali 16.3.6. Not sure of the path or if this is even a stable version. There are many options on Cisco.com. Suggestions? Just trying to get everything current.

Thanks

Hi
we used Denali it screwed up our IWAN DMVPN as well if you jump to Denali or Everest the RSA cipher will break remotely so you will have no SSH if your upgrading remote routers , the keys get killed

we test all our images with MVM and Prime this one came clean were running it on 70+ 4331s currently isr4300-universalk9.03.16.07.S.155-3.S7-ext.SPA.bin"

Thank you. That's what I had previously downloaded but wasn't sure how far behind we were. Sounds like we need weren't that far off with the S6. Take care
