Update Kernel

we've been advised, when updating kernels with up2date method, that we use the -i option instead of the -u option. My question is, if we do that, will it remove the existing backup kernel? This is our current grub.conf:

Code:

default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
# Primary kernel: default=0
title Red Hat Enterprise Linux ES (2.6.9-42.0.10.ELsmp)
	root (hd0,0)
	kernel /vmlinuz-2.6.9-42.0.10.ELsmp ro root=/dev/sda5
	initrd /initrd-2.6.9-42.0.10.ELsmp.img
# Backup kernel: default=1
title Red Hat Enterprise Linux ES (2.6.9-42.0.3.ELsmp)
	root (hd0,0)
	kernel /vmlinuz-2.6.9-42.0.3.ELsmp ro root=/dev/sda5
	initrd /initrd-2.6.9-42.0.3.ELsmp.img

this is on a RHEL ES release 4 (Nahant Update 5) Cpanel box.

TIA,

that's what I thought, I just wanted to verify before proceeding
