    Looking to upgrade our AOS version

    mstokes580 New Member

      We are currently running 17.03.05.00.E on the majority of our systems and we are wanting to move to a newer/sewest software. What would be the safest patch to move to from our current AOS? Should we upgrade 10 18.0.0.0 and go down the line and work our way up to R10.0.0 or should we go straight to R10.0.0 or is there a specific patch we should move to? We have a mix of 1st and 2nd gen devices... 1224's 1335's 1524st's

          Release notes are your friend.  No reason not to go to the latest code on all.  You will need to be careful verifying by part number as well as model what are gen. 1 vs. gen.2 devices as the firmware image different and gen. 1 likely won't take the most recent code.

           

          Making a big jump to the latest will probably just work, but rolling back may be tough. When upgrading, certain command syntax is modified automatically to allow for new features.  For example, many commands now have the "ip" keyword to distinguish from "ipv6" which wasn't supported in earlier code. If you need to roll back, the commands with a leading "ip" may not be understood.

           

          For consistency, you may want to only upgrade your gen. 2 devices to the latest code supported by gen. 1 so that everything looks and works the same unless you need specific features provided by later code on the gen. 2 devices only.
