[CentOS] Upgrading from WBEL and 4.2?

[Benjamin Smith]

Here's the script, wbel2centos4.sh 

#! /bin/sh
################################################################################3
#
#       wbel2centos4.sh - a script to change over a WBEL4 server to CentOS4.
#
#       see http://www.centos.org/modules/smartfaq/faq.php?faqid=19
#
#
#
# Step 5 is done BEFORE step 4 to eliminate possibilities of removed yum
# "cruft"...

arch="i386";

# 64 bit is not well tested.
#arch="x86_64";


# Step 1;
yum clean all;

# Step 2; RPM-GPG-KEY-centos4
rpm --import os/RPM-GPG-KEY-centos4

# Step 3;
rpm -e diskdumputils;
rpm -Uvh ./os/initscripts-7.93.13.EL-2.centos4.i386.rpm
rpm -Uvh ./os/centos-release-4-1.2.i386.rpm

# Step 5;
rpm -e yum;
if [ -f /etc/yum* ] ; then
 mkdir /etc/BLOAT;
 mv /etc/yum* BLOAT;
 fi;

# step 4;
rpm -Uvh ./os/centos-yumconf-4-4.2.noarch.rpm
rpm -Uvh ./os/yum-2.2.1-1.centos4.noarch.rpm

# set up the repos
rsync -vaz --delete yum.repos.d /etc

# Step 6;
yum -y update;

exit 0;
