Hi,
I have 2 5508 WLC in a HA SSO cluster and want to upgrade the FUS. I've been looking for informaiton about this. My questions is:
Do i need to split the HA SSO and upgrade the WLC one by one?
Or
Will it work the same way as a software upgrade? Means, i will only upgrade the primary WLC and the image will be transfered and installed at the secoundary.
Best regards,
Per

Depends on what is the current firmware the two controllers are running on.

Hi Per,
Just wonder how was your FUS upgrade on the HA SSO WLC? Did you need to unpair them first?
We are going to upgrade our HA SSO 8510 cluster to FUS 2.0.
Many thanks,
Edward
