During Migration from 6.1.5 to 10.5 with PDC, i encourtered a DNS issue. The first Call manager (Publisher) has an old Domain Name in the Certificate Management (CallManage.pem) and the Domain does not exist any more and it cause the CallManage 10.5 software installation to fail. The Secondary Call Manager is fine, and has the currect Domain Name.. How can i regenerate a new Call Manager Certificate that point or shows our current Domain Name in CallManage.pem?
self-signed certificates in Cisco Unified Communications Manager servers (CallManage.pem) need to be change or regenerate..
Please any ideal or help would be appreciated...
Regards

Hi
It is under the OS Administration > Security > Certificate Management > Generate Self Signed Certificate.
You may want to restart the cluster after the Certificate Generation

Hi Samuel
Thanks for your concern. The issue am facing is changing the CA CallManager.pem or .der CN=CUCM01.mydomain.com into Company.com Name..
Cert, Self-signed certificate generated by system.
Is there any execute CLI command to change CA CallManager.pem CN?
Thanks

Hi Desmond,
Once you change the hostname, it automatically updates all the Self Generated certificates, you dont have to do anything about it.
