Thanks every one for all your help,
using VNC seems to be a good option for those who has no access to console and want to install Centos remotely, however just to test , I tried to upgrade Centos 4.5 to Centos 5, but it progressed almost to the end and then stoped with some error. nothing upgraded.
I think I should first upgrade it locally and then start doing it remotely.
fresh install will leave a lot of files from previous version, so it should not be considered at all.
is there any log file that shows why upgrade failed ?
When doing an upgrade, you need to remove as much custom or added rpms as possible. I remember old upgrades on redhat 7 would fail silently if you had linuxconf installed. Have a look at http://wiki.centos.org/HowTos/MigrationGuide
