Hi

   Pretty straightforward. If we were talking about a very large environment, I´d recommend to pre-download AP images, but, that´s not the case.  Just go for it.

Read the Release Notes very carefully. It is not possible to go straight from 8.2.X.X to 8.5.X.X without upgrading to 8.3.X.X first.

The first step in any upgrade is to check the compatibility of the WLC/ APs with the code version. In your case they all are supported on 8.5.140: https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html

I will quite often do a pre-download to the APs. 

Plan on at least 30-40 minutes for the APs to reload, upgrade etc when you hit reload on the WLC
