ISE on VM - will changing DNS (ip name-server) cause any issues or requires license rehosting?

[cwwong1973]

As per above, the DNS needs to be updated as the old ones has been decommissioned.

Will there be any impact if we update the "ip name-server" entries for ISE running on VM (ISE-VM-K9)

Concerned about license rehosting or  other major impacts.

Thanks in advance.

Not if it's just a new DNS server, but if you are AD joined, it of course still has to be able to resolve the AD in DNS. I think it might ask you to restart the service once you change the setting.
