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.

Basically:

yum clean all
yum update glibc\*
yum update yum\* rpm\* python\*
yum clean all
yum update
shutdown -r now
