topic Yes, you'll need to upgrade in Wireless

Do I need a new FUS image when upgrading controller code?

tdennehy — Mon, 05 Jul 2021 08:21:38 GMT

We want to do the upgrade on WiSM2sfrom 7.0.220.0 to 7.4.121. for two modules. 
We want to support a license for 1000 APs.
Both wisms are running field recovery image 7.0.43.32
No HA configured.

How do I determine if I need to install a new FUS image when I upgrade the code? Is there a matrix out there that I cannot seem to find?

Thanks in advance.

Yes, you'll need to upgrade your FUS image as well, to 1.7.0.0

When you look at the release notes in the upgradeing software section it should tell you what FUS shoudl be running.
