Upgrade Controllers from 4.2.130.0 to 4.2.176.0

I'm planning on upgrading the software of all our controllers from 4.2.130.0 to 4.2.176.0. The release notes state the Cisco Unified Wireless Network Controller Boot Software 4.2.112.0 ER.aes is required. Should I upgrade to 4.2.176.0 first, reboot, then upgrade to 4.2.112.0, then reboot?

Make sure you are not using a 2106 that one doesnt support this ER.aes file.

I suggest that you make a backup of your config, upgrade the bootloader and then the WLC code to 4.2.176.0

Would you be able to confirm if the latest boot software file (4.2.112.0 ER.aes) is required when using WiSM software 4.2.130.0 ? I guess my question is what boot software should I be using if I'm currently using a WiSM with 4.2.130.0 software? At the moment I'm using 4.2.205.0 bootloader version.

I'm having to re-install the WiSM IOS to one of my controllers to 4.2.130.0 due to possible corruption. Currently this controller is in production and supporting up to 138 AP's at the moment. As I'm trying to add new AP's they keep erroring out with unable to Tar file, and I've tried with 3 other new 1130's. However, when I pointed the AP's over to a different WLC within the same mobility group they joined with no problems and were able register and download it's software.

My peers who've had this same issue in the past had to re-install the WiSM IOS.

Greatly appreicated.
