LEL 4.0 uses udev device file system and because of that the only 
reliable way to upgrade is booting from installation disk(s). You can 
use nfs/ftp/http/images on hard disk installation methods, the important 
thing is that the installation environment is LEL 4 based and 
understands udev. I haven't yet tried upgrade, so you should write 
"linux upgradeany" at the boot prompt.

If you want to use SE-Linux, a clean installation is preferred because 
ext3 has some SE-Linux spesific extentions in 4.0. This is more of an 
opinion, there may be a way to add them later.
