This web page describes upgrading for any Scientific Linux 6.x distribution. Simply replace anyplace that says 6.x or 6x with the appropriate version number. So if you were upgrading Scientific Linux 6.2, then you would replace 6.x with 6.2, and 6x with 62 wherever you see it in this document.

Before You Start

Although anaconda provides an option for upgrading from earlier major versions of Scientific Linux to Scientific Linux 6, we do not recommend this.
In-place upgrades across major releases do not preserve all system settings, services or custom configurations. Consequently, we strongly recommends fresh installations when upgrading from one major version to another.
