Downtime when chaging DNS IP

Hello - I need to change IP of the DNS server under Setup - Services on our Panorama, FWs and Global Protect devices. Would like to know what kind of downtime I can expect with the cutover to the new IPs especially on t he FWs and VPNs.

@JJoseph,

Modifying the DNS servers won't cause any downtime. Migrate to the new DNS servers and shutdown the old DNS servers once you've verified they are no longer receiving any requests.
