Have a centralized call processing cluster over an IP WAN.
When you go to CUCM Admin / System / Server, you see Host Name / IP Address with IP addresses and the cooresponding names / descriptions.
Does anyone have the process steps for changing the existing DNS server IPs ?
Is this just a matter of accessing the CUCM Pub / Subs and via CLI and doing a " set dns primary <ip addrs> and then settting the secondary via "set dns secondary <ip addrs> and then do the same for each subscriber?
Is there any required changes for the cluster ELM ?

Hello Nadeem,
Thank you for the super responsive reply..!
I see a couple different comments about having to make any changes to the ELM and if a license rehost would be needed or not... was there a conclusion or consenus on having to rehost license files?
Thx... Ron

as already mentioned but yes last post was really make chaos out here. but this does not required to re-host the license you just need remove PI and re-add before and after changes
admin:set network dns primary X.X.X.X WARNING: To avoid license synchronization failures, delete the product instance from the Enterprise License Manager managing this server's licenses before changing network settings.You will have to re-add the product instance after the network settings have been changed.
