As far as I know, upgrading between major EL versions is not supported.
A full re-install is recommended.

Currently, the OS is installed on a vmware, and arcording to the tech staff,
due to technical, they can not install CentOS 6 or anything other than CentOS 5.4 :)


If you wish to try anyway, you will probably need to change the repos to
point to the EL6 repos instead of the EL5 repos.

This seems reasonable (yet a little risky) and I definitely will try to do that.
Anyone has done that before?
