Upgrading RHAS 2.1 to RHEL 3.0

[Said MOKHTARI]

Make a full backup of the system

make a backup of /home, /usr/local/ibm, /etc/passwd, shadow
sysctl.conf,  and so
install RHL 3 (if possible preserving your initial partition and out
formating /usr and /home)

apply the requirement of  webspher on RHL3

test the new install
