Can we stop propagating newer firmware for Aps after upgrading WLC?

[Suchi]

Hi ,

We have a centralized Cisco 5508 WLC with 84 APs(1142N) in branches (slow WAN links), Current WLC  IOS version is 7.0.220.0.

Recently we bought new Aps Air CAP36021-N. These APs are not compatible with existing WLC IOS.  If I upgrade WLC, then can I stop propagating newer firmware for old Aps? Because it kills all WAN. What is the best way to do this?

Appreciate any suggestion

That defeats the true purpose of controller-based IOS.

You can schedule the WLC to upgrade the IOS after office hours.

Yes I know your point is valid, but now I want to stop upgrading old Aps for few weeks. How can I do it? Because once I upgrade controller, it restarts & all Aps try to connect & grab new image. How can I stop it? Is it possible to stop before upgrading WLC?
