Software Version Upgrade for Cisco 4402 Wireless Lan Controller

[PRASAD BAIT]

Hi,

We have Cisco 4402 Wireless Lan Controller with Software Version 3.2.171.6 and we want to upgrade it to latest version.

So can anyone please let me know the latest version to upgrade the WLC?

Also since WLC is running on very lower version is it possible to upgrade to the latest version directly or we have to move it step by step to upgrade this to latest version?

Thanks

Take a look at the compatibility matrix below:

http://www.cisco.com/en/US/docs/wireless/controller/5500/tech_notes/Wireless_Software_Compatibility_Matrix.html

7.0.235 is the latest that you can go to:

http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn7_0_235_0.html

The release notes outline the upgrade process.

"Upgrade to 4.0.206.0 or later 4.0 release, then upgrade to 4.2.176.0, before upgrading to 7.0.235.0."
