Compatibility of APs when upgrading to 8.5 on a 5508 Wireless controller

[craig.rogne1]

Currently have a 5508 Wireless controller running 8.0.133.0

Purchased a new Aironet that requires version 8.5 or better

Currently have a bunch of AIR-CAP3602I-A-K9 running on 8.0.133.0.  Will there be a problem with these controllers when attempting to update to the 8.5 version on the controller?

The 3600 AP will work after upgrade the code.

Last firmware support for the 3600 is 8.5.X.X.
So you are good to upgrade to 8.5.X.X.

WARNING:  Read the Release Notes for 8.5.X.X very, very carefully.  It is NOT POSSIBLE to directly jump from 8.0.X.X without going through an intermediate version like 8.2.16.X.X first.
