ISE 2.4 change DNS servers

[densto]

Hello,

We are running ISE 2.4 p10 6 node cluster with 2 admin and 4 psn nodes.

Migrated our AD and DNS servers to Azure and I am in process of reconfiguring ISE with new DNS servers.

Based on ISE CLI Reference Guide after changes are made you must restart Cisco ISE.  Does it mean to reboot it or running: 

application stop ise
application start ise

will be enough?

Thank you

i would prefer to reboot the ISE appliance - any way you doing this change in maintenance window.

I did that when updated dns config on PSN nodes.

I want to find out if restarting ISE application is enough when changing DNS servers in ISE.

Thank you

Service restarting should work for you, but if you have maintenance window, reboot when you get apportunity.

Dear @balaji.bandi 

Could you provide the document reference required to restart the service and reboot Cisco ISE when changing DNS for Cisco ISE Version 2.7?
