Certificates change on secure-cluster

[Francois Lieuze]

Hi everybody,

One of my customer has a secure cluster of 2 CUCM and I have to deploy a new CUCM IM & Presence cluster on that installation. When I did the initial installation, I didn't configure any domain name or DNS server, and I know that will be a problem with Jabber : users will have to validate a security message about certificates.

So, I want to set dns server and domain names on the CUCM. And this will generate new certificates. I did that before on NON-SECURE clusters, the only thing to do before is to check the "Prepare Cluster for Rollback to pre-8.0" enterprise parameters to empty the ITL File. But what will happen in the case of a SECURE cluster ?

Thank you in advance for you answers.

Regards,

François Lieuze

Hi Francois,

As per the following doc 'If you use CTL files or tokens, re-run the CTL client after you change the IP address or hostname of the server, or after you change the DNS domain name.'
