Hello All,
I have a CUCM Pub and Sub running CUCM 11.1.5. The cluster is currently in production. I'am going to be doing Jabber and I have a IM and P server on 11.1.5 already running DNS. I migrated a cluster to 11.1.5 so It didn't have DNS enabled to being with. What exactly are the steps for me to enable DNS on both my Pub and Sub? It is in production with phones registered, so I don't want anything to happen that might cause me to need to manually delete ITL files on phones. Is this the right steps to take?
Subscriber -
1. set network dns primary
2. set network dns secondary
3. set network dns
Subscriber reboots and phones fail back to PUB.
Wait for subscriber to come back online and for phones to register back to subscriber.
Publisher -

Publisher reboots.
Thanks
