That will soon (within two weeks) be on the "How To Upgrade To The Latest Release" web page at https://www.scientificlinux.org/documentation/howto/upgrade But the steps will be similar to what they are for SL3.0.x. But the first step will be a different link. you will do rpm -Uvh ftp://ftp.scientificlinux.org/linux/scientific/4x/i386/misc/RPMS/yum-conf-4x.SL.noarch.rpm yum update yum yum update If you just do a 'yum update' without updating your yum-conf, then you will still be at S.L. 4.0. That is one of the ways that we are different that CentOS. We have several experiments and sites that want to sit at a certain release and only get the security updates. They don't want to automatically be upgraded to the latest release. So we make the updating to a different release a manual process. We are working on a way so that people who do want to just automatically be moved up to the latest release, can have this functionality. But that will be a couple weeks away.
