Changing DNS server addrresses on CUCM 9 cluster

[Derek McCormick]

Hi

I am running CUCM 9 cluster and need to change the DNS server ip addresses configured on each server. Is it just a matter of chaning the ip addresses on the cli

set network dns {primary | secondary} ip-address

and then rebooting the cluster? Do i need to rehost the License files in ELM or should the current license files work?

Thanks,

Derek

Hi Derek,

No.

Licenses remain same.

Hi Derek,

Just a small note to add to my friend Aman's good tips (+5)

This query did come up recently and you won't have to re-host

but there are some related ELM steps to consider
