I would like to upgrade our three WLC 4402 controllers from version 184.108.40.206 to 220.127.116.11. I have downloaded the two files (AIR-WLC4400-K9-7-0-235-3-ER.aes and AIR-WLC4400-K9-7-0-235-3.aes). Which one should I upgrade/install first? I haven't seen this in the release notes (http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn7_0_235_3.html#wp889732)
Thanks in Advance.
