5508 WLC Upgrade steps

Troy F — Mon, 05 Jul 2021 07:52:50 GMT

Single 5508 WLC with 8 x 1142 APs.

5508 is running FUS 1.3, software version 7.0.116.0, field recovery image 6.0.182.0.

I need to bring the software version up to at least 7.2.115 to support 2 new 2602 AP i need to install.

Question is; do I install FUS 1.9 then update my controller to 7.6.120 or do I need to do any intermediate steps?

This is my first time upgrading a WLC so I'm fresh and this is a production WLC.

Cheers

Hi Fisher.

Normally It doesn't matter as long as you get it done but make sure that you reboot the WLC before doing the next.

Here is the procedure for FUS upgrade:

Thank you both for the replies, I'd already got the documents for the WLC and FUS upgrade, but the tutorial really simplified it. Thanks.
