[cisco-voip] Renewing TVS and IPSec certificates

[ROZA, Ariel]

Hi guys,

I have some specific questions regarding renewing some certificates.
The situation is this. In a cluster with 4 servers, I have two of them that have their tvs.pem and ipsec.pem certificates paste their due date.
I have reviewed a lot of the documentation available, and designed a step-by-step procedure to renew them, doing so one server at a time, stopping the TFTP, etc.

But still I have some specific doubts:

If I just want to renew the ipsec.pem cert ¿Do I have to go through the complete process to renew the ITL and reset the phones to get it? Or can I just renew the self-signed cert and restart the DRS Services?
If I am using mixed mode ¿Do I have to regenerate the CTL file as well?

Regards,
