Yes.

Good reason...

Oh, you actually wanted instructions.... okay...

Are you doing this for all your virtual hosts?  If so it's actually
quite easy:

Copy all the virtual host blocks from /etc/httpd/conf/httpd.conf; they
begin with the first instance of:

 NameVirtualHost 63.108.93.101
 <VirtualHost 63.108.93.101>
 ServerName www.nobaloney.net

and end with the last:

 </VirtualHost>

(IP#s are just an example; these lines come from my own virtual host
block for nobaloney.net).

and create a new file called "oldip.include".  Paste all of this into
the new file.

LEAVE the original lines in the /etc/httpd/conf/httpd.conf file, and at
the bottom of the file add the line:

 Include /etc/httpd/conf/oldip.include

Then do a global change on /etc/httpd/conf/httpd.conf, changing all the
old IP#s to the new ones.

Then reload httpd as follows:

# /etc/rc.d/init.d/httpd reload

That's it.

In a week or so, delete the oldip.include file, remove the Include line
from the bottom of the httpd.conf file, and reload httpd again:

# /etc/rc.d/init.d/httpd reload

to clean up your system.
