ISE, NAD question

What happens if I change the hostname of a switch that is already configured as a NAD? I’m assuming all dot1x authentication request will fail because the switch hostnames don’t match what’s in ISE’s network device list database.

For example: I change a switch’s hostname from A to B (IPs remains the same, 1.1.1.1). ISE has an entry for A-1.1.1.1 and no entry for B. All dot1x authentications will fail.
