You may not have the latest version of yum or some of the plugins ....
Please do this command (all one line):
rpm -q yum python yum-metadata-parser yum-utils yum-protectbase
The results should be this for the latest versions:
package yum-plugin-protectbase is not installed
If you have yum-plugin-protectbase (and not yum-protectbase) installed,
you need to replace yum-plugin-protectbase ... that is the old version
Also you need to review the plugins directories if you had any plugins
installed in CentOS-4 (/etc/yum and /etc/yum/pluginconf.d) to make sure
there are not any <file_name>.conf.rpmnew files.
You currently have installonlyn and protectbase enabled ... I would
recommend that you properly configure your CentOS-Base.repo to use
yum-priorities instead of yum-protectbase.
Also, if you are using the CentOS-Base.repo file and if you are using
the "mirrorlist" option instead of some specific "baseurl" mirrors, then
I would also recommend the yum-fastestmirror plugin.
Please see this link for plugin install and configuration:
BTW, upgrades are not normally clean. I personally recommend that
people never upgrade, but instead backup their data and do a fresh
install, then move data over. The upstream provider also recommends this:
Read specifically the first four paragraphs under the title:
"23.1. Determining Whether to Upgrade or Re-Install"
