HA 9800

[nstr1]

I have a virtual Cisco 9800 soon, I will have a fiscal Cisco 9800.
Is it possible to have an HA between my virtual Cisco 9800 and my physical Cisco 9800?

 Must be both vritual or both physical.

Hi,

You will not be able to use HA-SSO, but with 2 different WLC's you can use N+1 HA.

Below link should provide you with some information on how to setup;

Basically you need to match the IOS-XE codes, match all the WLAN related configuration and configure RRM properly.
