  to RHEL/CentOS 3, including all current updates.
• Kernel update to most recent RHEL/CentOS Kernel - 2.4.21-27.0.2
• Refresh your cPanel to the RHEL/CentOS build.
• Recompile Apache to 1.3.33 and PHP to current releases of 4.4.0
• Update Exim to current RHEL/CentOS release
• Update firewall script if needed to support newly assigned IP blocks (such as 70.x.x.x.)
