WLC Upgrade

[mi204978]

Hello,

I would like to upgrade our three WLC 4402 controllers from version 7.0.116.0 to 7.0.235.3. 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.

Kind regards

Michael

Go ahead and do the code first then the ER code. You will be fine.

Btw to lessen downtime you can do a preimage to your aps. I blogged about it here ...
