I'm trying to follow the steps from the MigrationGuide (modified to reflect the fact I'm dealing with non-current versions) to migrate from RHEL 5.1 to CentOS 5.1. I used the following commands:
# rpm -e --nodeps redhat-release-notes redhat-release yum-rhn-plugin redhat-logos
# rpm -ivh http://vault.centos.org/5.1/os/x86_64/CentOS/centos-release-5-1.0.el5.centos.1.x86_64.rpm http://vault.centos.org/5.1/os/x86_64/CentOS/centos-release-notes-5.1.0-2.x86_64.rpm
# yum update
This fails on the yum update
step with an error claiming there's a conflict between e2fsprogs and the kernel. I've included a more detailed error below.
# yum -d7 upgrade kernel

Check if the 32 bit version (i386,i586,i686) of e2fsprogs exists in your system and remove it if you don't need it.
As HD says, there's a known bug in older versions of yum that if there is 2 or more conflicts ona single package yum will fix the first one and then bail on the second (here conflicts for both .i?86 and .x86_64 count one each).
You can either get a beta version of yum for 5.4, or remove one of the arches ... or manually update e2fsprogs as well (so there is no conflict).
