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.
