8.3.143 vs 8.5.135

bvj197222 — Mon, 05 Jul 2021 16:31:14 GMT

We have two 5508 in a HA-SSO cluster. Currently we're running 8.3.140, and we want to Upgrade it due to some strange problems we have With Our 2800 AP's. We also have 26xx and 27xx AP's on the same Controller. Which Version should we Upgrade to, 8.3.143 or the latest 8.5.135? I read that the latter was buggy when it first came out, but what do you guys recommend?

I'm with Rasika & go to 8.5.140.0.
Read the Release Notes so you can determine if the APs are supported in 8.5.140.0 or not.

Thank you for Your reply. I have upgraded to 8.5.140 now and the SSO-cluster came back online, unlike when I tried an Upgrade to 8.5.120: https://community.cisco.com/t5/wireless-and-mobility/pmalloc-double-free-crash-after-upgrading-to-8-5-120-0/m-p/3352217#M97909

Upgrading to 8.5.140 fixed problems on two of Our sites. Those two sites only had 28xx AP's. We also have about 20 sites who had 26xx and 27xx, and those sites didn't experience any problems.

Site A: Users loosing their wifi-connection randomly. Different error Messages in the log but nothing specific.

Site B: Users loosing their wifi-connection randomly, AP's booting randomly as they lost contact With the Controller at headquarters (CAPWAP error)

Upgrading to 8.5.140 fixed both problems.
