Changing DNS Ip address on CUCM/Unity v10

[ev1205]

Hi everyone, we are implementing a new CUCM BE6K ver10.5, with not subscriber servers

During installation our customer changed DNS Ip addres and NTP Ip address.

We just need to confirm proper procedure to change DNS Ip address on our CUCM, as we have read we must:

a) From CLI: set network dns primary X.X.X.X

b) Reboot server.

But we are not sure if we have to delete and recreate the ELM product instances for our CUCM and our Unity servers

Thanks in advanced for your support

best regards

Hi Enrique,

just go through this thread

https://supportforums.cisco.com/discussion/12089806/changing-dns-server-addrresses-cucm-9-cluster

secondly, what I understand since it is a migration on new hardware , so u need to create a new product instance and generate text file and share it with licensing team .
