Why do you want to upgrade?  Is something not working or do you just 
want the latest of each package.

You can basically use any of the instructions in LFS Chapter 6 to 
overwrite most packages.  The biggest problem is updating glibc.  When 
you need to do that, we recommend you just rebuild a new system.  Don't 
update the linux headers.  They need to be the same ones used to build 
glibc.

Personally, I don't update unless I have a specific need.  I have a 
separate system for LFS development.

Also for BLFS packages, it can be a problem to update something like 
xorg while the current system is in use unless you use a different 
prefix like /opt/xorg-xx instead of /usr.
