[Solved]How to change the default domain name?

[Macsloverd]

I have a ispcp Server running for 2 years and it is running very well. However, I need to change the default domain name of the server to another one. e.g. :

the current domian name is [abc.com] and [admin.abc.com] is the CP login. And now I would like to change it into [efg.com] and the CP login would be [admin.efg.com].

The IP Address is the same.

The version of the ispCP that I am using is 1.0.5 build: 20100331; upgraded from 1.0.4.

Is here anybody who had ever done this before? Or anyone who knows how to achieve this? I will be very appriciate for any help. Thanks in advance.

The solution to this issue is posted as reply by nuxwin works perfect and I summarize it here for people who might find it useful.

Step One:
Change the data in both /etc/ispcp/ispcp.conf and /etc/ispcp/ispcp.old.conf

Code:

BASE_SERVER_VHOST = admin.abc.com

TO:

Code:

BASE_SERVER_VHOST = admin.efg.com

Step Two:

Code:

mv /etc/ispcp/bind/working/admin.abc.com.db /etc/ispcp/bind/working/admin.efg.com.db

Step Three:

Code:

cd /var/www/ispcp/engine/setup/
perl ispcp-update

That's all!
