You should always yse the same architecture for an upgrade. A yum upgrade should be possible following the release notes. The $basearch variable in yum should point to the correct packages. http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.4 Basically: yum clean all yum update glibc\* yum update yum\* rpm\* python\* yum clean all yum update shutdown -r now
