HELP!!! Are there any downtime if we change clearpass hostname?

We have an aruba controller and a clearpass server that is configured for authentication and authorization and in production. What will happen if we change the hostname of our clearpass server? Thanks

If you're using PEAPv0/EAP-MSCHAPv2, you may have to rejoin it to the domain which could result in a few minutes of downtime. But I assume you have another server correct? Stop the RADIUS service on one of them so the NAD will mark it out of service, then make the change and start the service. Rinse and repeat
