Hi Jubair,

In N+1 mode:

Either Both WLC must have enough AP license.

or

Primary WLC have AP license and 2nd WLC have HA-SKU license.

As soon as an AP joins the HA-SKU secondary controller, the 90-day timer starts, and the user sees a warning message after 90 days. In other words, an HA-SKU controller can be used as a secondary controller for 90 days without a warning message.

To do HA on already purchased hardware, you need to have 50 AP licenses on them.
