I considered upgrading my workstation from CentOS 5.6 to SL 6.0, and

As I keep many important directory trees on different partitions (for
reasons I can discuss under separate cover), I basically did a complete
copy of the system trees from which I would need to restore files.
/home is on a different partition, and thus the install did NOT clobber
it because I instructed the install process not to do so.
Note that I did NOT repartition the hard drives, nor did I change to any
other filesystems than those already on the partitions being clobbered
by the (partial) fresh install. There was a comment as I recall from
Connie Sieh as to which directory trees had to be a fresh install, and
those I did.
All system directories should be part of the hard drive "format".
Leaving some system directories to get "clobbered" will lead to mixed
results. Format all system directories during the new SLF 6.x install.

The result booted fine, and by restoring what I needed from the saved,
unclobbered copies, I had everything I needed. The only glitch I had
was the issue of polymorphism: I needed X86-64 as a base system, but I
also needed to run a number of IA-32 applications. My Centos 5.6 was
IA-32. I now seem to have solved the polymorphic issues for my the
instance of my particular workstation configuration.

Hello all,
Do you still need to upgrade with media to go from SL5 to SL6, or can I
do it from a CLI?
thanks,

To be explicit, am I correct that these system directories are:
/boot
/etc
/usr/bin , /usr/sbin , /usr/lib
/lib
/var
plus the MBR to point to the correct boot loader?
Are there others that I have forgotten?
