What is a 301 redirect?
==================
A 301 redirect is the preferred method to preserve your current search engine rankings when 

redirecting web pages or a web site. The code "301" means that the page has "moved permanently".

How to set up the 301 Redirect?

    To create a .htaccess file: open notepad, name and save the file as .htaccess. (be careful not to 

save the file as txt)
    If you already have a .htaccess file on your server, download it to your desktop for editing.
    Copy this code into your .htaccess file: 

redirect 301 old.htm http://www.domain.tld/new.htm

    If the .htaccess file already has lines of code in it, skip a line first
    Save the .htaccess file
    Upload this file to the root folder of your server.
    To test it, simply try to load the old site or page in your browser. You should be redirected 

immediately

How to change the primary IP addres of a WHM/cPanel server
==================
Refer this http://www.codero.com/knowledge-base/questions/248/How+to+change+the+primary+IP+addres+of+

+a+WHM%7B47%7DcPanel+server

Steps in WHM:

Log into WHM and go to Basic cPanel & WHM Setup
Change the Primary IP here with the option that says "The IP address (only one address) that will be 

used for setting up shared IP virtual hosts"
Note: This might not actually be necessary.
Log in to SSH, and do the following:

Edit /etc/sysconfig/network-scripts/ifcfg-eth0
Change the IPADDR and GATEWAY lines to match the new IP and Gateway for the new ip
Edit /etc/sysconfig/network
Change the GATEWAY line here if it does not exist in the ifcfg-* file.
Edit /etc/ips
Remove the new primary IP from this file if it is present
Add the old primary IP to this file with the format <IP address>:<Net Mask>:<Gateway>
Edit /var/cpanel/mainip
Replace the old primary IP with the new primary IP
Edit /etc/hosts
Replace the old primary IP with the new one if needed. The hostname's dns will need to be updated too
Restart the network service to make the new IP the primary
service network restart
Note: You're probably going to be disconnected at this point, and have to log in to ssh using the new 

primary ip.
Restart the ipaliases script to bring up the additional IPs
service ipaliases restart
Run ifconfig and make sure all IPs show up correctly
Update the cpanel license to the new primary IP
Verify you can still log in to WHM and there is no license warning
