Read the Release Notes.  

And why pick 8.3.130.0?

HI Leo；
Our customers want to upgrade to this version, so we only do things according to the customer's wishes.But，i cannot find a description about that.

What Leo is suggesting is to take a look at the release notes and then the open caveats that is listed. Review that piece so that you know what issues there are on that release. It’s also a good idea to point out risk to the customer especially if you are a consultant. If a customer request a certain code, then at least call out the risk so that you are covered.

Hi Scott
thanks for your explain.I will tell my customer this version’s advantage and
Disadvantage.But,I still want to know the need about upgrading 7.0 and 7.2 to 8.3.130.0.
Thanks ~

Ask the client if they know about KRACK.

[Scott Fella]

You should see a section about upgrades. That section will explain what versions can directly go to the version you want or if the upgrade had to go to another version first prior to the final code. Read that as that is the key.

I would definitely avoid 8.3.130 if you can. We are running that since February when KRACK was patched but having so many issues with it. APs drop and crash as well as roaming issues.

Cisco told us to go on 8.5.120 so we are doing that next weekend.

Previously we were on (a long time ago) 7.4 then jumped on 7.6.130 and then to 8.0.121. From there you can go to any version. If you are running 7.0 though, you must have some old APs, you might not be able to go on 8.3.130 and above if you have legacy APs. Otherwise, code 8.2.166 is very stable too.

Cisco now recommends s 8.0.152 all of a sudden.

Serge.

8.5.130.0 coming out in the next 24 hours.

[denizyaran]

Thanks Leo. I guess that supersedes the 8.5.120? Did you try it at all?

[Leo Laohoo]

I didn't try 8.5.120.0 because I'm holding out for 8.5.130.0.  

[denizyaran]

Cool, we have been testing 8.5.120 for a month now. Very stable. Used with APs 3600, 3700 and 3800.

Running the beta of 8.5.130.0 in my lab now since a week, so far running nice. I suggest you await that version.

[denizyaran]

Thanks. Will test it before Saturday.

Hello everybody， Thanks for your advice，and i will suggest my customer to use a tac recommend release.Maybe，I will make the upgrade from 7.0.116.0 to 7.4(first upgrade FUS 1.7),and then, to 8.0(first upgrade FUS 1.9),final to 8.3 or 8.5. now,the old aps are AP1040,so maybe it’s ok.
