Update WLC or WCS first ?

Hello

In which order should WLC and WCS be updated or doesn't it matter ?

Re: Update WLC or WCS first ?

from the release notes of WCS 4.1.191.

"In order to be compatible, the Cisco WCS release must be at least the same release or a later release than

the software release running on the controller. For example, Cisco WCS running release 4.0 cannot

manage a controller running release 4.1. If an upgrade is planned, upgrade the Cisco WCS first to

eliminate any unexpected issues. Cisco WCS supports database upgrades only from the following

official Cisco WCS releases:"

I have always upgraded the controllers 1st, and then the server; all the way up to 4.2.112.0. That may change in the future though...
