How to do firmware upgrade If there are two type of Mobile Express APs?

[lvlingsheng]

Hello:

I checked the doc for updating the APs firmware in Mobile Express:

Cisco Mobility Express Deployment Guide - Managing Mobility Express Network [Cisco 5500 Series Wireless Controllers] -…

It says:"If there is a mix of 1800 series and other supported Access Points, TFTP must be used as the transfer mode."

So if I have a 2800 series, and a 1850 series, the update is still the same as in document?

Update two APs separately?

Thanks
