Is there a way to change CCM server hostname before/during upgrade?

[sgavan]

Upgrading a server on 3.2 to 3.3 but it's hostname has an "_" in it which causes some issues with name resolution.

Looking for a way to change the hostname on the server if posible.

The following document will be the right one for your issue:

Thanks for the link... however I don't see any info on changing the server name during the upgrade. Anyone know if this is even allowed? We can get around the DNS issues by using the IP address, but since we are making a major upgrade we wanted to fix the name as well.

Thanks!

There is no supported way currently available to change the server name of a system running Cisco CallManager.
