Please read the scientificlinux site before making your questions here.
In the scientificlinux site you can read this:

How To Upgrade To The Latest S.L. 5.x Release
Scientific Linux was designed so that an administrator can easily
upgrade their computer between minor releases.
It is not required that administrators upgrade their release, because
the security errata will be updated for all releases. But there are
often features and/or packages included in later releases that were not
available with the earlier releases.
Below is the steps, for both yum and apt, to change to the latest 5.x
release.
These instructions are for updating between minor releases, such as from
5.0 to 5.1. Changes between major releases 4 and 5 (such as from 4.2 to
5.1), cannot be done with yum, but must be done with the main installer.

You can read more here

The site is the first source of information and a indication about what
questions are pointless.

Best wishes 

Arturo
