Forgive me if this has been answered before, but is there a page
detailing how to convert a TUVL4 system to SL4?

Hi,
This question comes up every year or two. We haven't made it into a web
page because we don't want to make it look like we are trying to take
away RedHat's business.
Updating from RHEL5 to SL5 is easier than it is to update from RHEL4 to
SL4. This is because RHEL5 has yum, while RHEL4 is using up2date.
I *believe* the easiest way would be to change up2date to point to
scientific linux, and then use it to install yum and the first updates.
1 - Edit /etc/sysconfig/rhn/sources and comment out the line
up2date default
and add the lines
yum fermi-base
http://ftp1.scientificlinux.org/linux/scientific/4x/$ARCH/SL/RPMS/
yum fermi-errata
http://ftp1.scientificlinux.org/linux/scientific/4x/$ARCH/errata/SL/RPMS/
2 - Install yum using up2date
up2date install yum
up2date install yum-conf
3 - install sl-release using yum
yum install sl-release
4 - Update everything else
yum update
You may run into problems with this, but I currently don't have the
infrastructure to test this out, so I am not sure what problems you will
run into. But that is the general idea. Get yum on the system, then
update sl-release, and then update everything else.
