Thanks fpmurphy!...It worked !...I followed your steps and upgraded to CentOS 5.8.
I have couple of queries which I could not understand during the upgrade. Kindly clarify the below queires:
1.I have image CentOS 5.8 ISO image in the hard drive and I tried to mount this to virtual machine running with CentOS 5.7 and it got mounted as (/media/CentOS_5.8_Final). When I checked the contents in the mounted directory (/media/CentOS_5.8_Final) , i could see lot of release notes and few directories like isolinux,Centos,etc.,. but unable to find the ISO image file..
In this scenario, i was unable to perform the upgrade.Later I burnt the Centos 5.8 ISO image file in the DVD and mounted it. By doing this , i could see the ISO image file .
Please clarify what is the difference when we mount the ISO image from the hard drive and the same image burnt in DVD ?
2.I mounted the ISO image and ran "yum list"..and got error. Later then I connected my system to internet and re-run "yum list" and it worked.
To upgrade from 5.7 to 5.8 , Do we need internet connection mandatory, without internet connection can't we do the upgrade.?.
Please clarfiy these two questions..so that it would be helpful to understand.
Thanks,
Ananth

pkg2du
pkg2du(1M) System Administration Commands pkg2du(1M)
NAME
pkg2du - convert driver packages to Driver Update format
SYNOPSIS
/usr/bin/pkg2du [-f] [-v] [-d dir] [-o iso] [-l label]
[-r release] pkg [pkg ...]
DESCRIPTION
The /usr/bin/pkg2du utility takes one or more packages as input and converts them to Driver Update (DU) format. If the -d option is speci-
fied, the resulting DU directory tree is placed in the directory dir. If the -o option is specified, a Solaris ISO image of the DU direc-
tory tree is written in the file iso. The ISO image can be burned onto CD/DVD using cdrw(1) or cdrecord(1) (not a SunOS man page) and used
during Solaris installation.
At least one of the -d and -o options must be specified. If both are specified, then both an ISO image and a directory tree are generated.
OPTIONS
The following options are supported:
-d dir
Directory where the DU directory should be created.
-o iso
Create a Solaris ISO image of the DU directory.
-f
If dir/DU or iso exists, remove it without asking first.
-l label
Label/volume name of the ISO image (if -o option is specified).
-r release
Solaris release number to use. It takes the form of the return from uname -r command, for example, 5.10. If unspecified, the release
number of the currently running Solaris is used.
-v
Verbose. Multiple -v options increase verbosity.
OPERANDS
The following operands are supported:
pkg [pkg...]
One or more packages to be converted to DU format.
EXAMPLES
Example 1 Creating a DU CD/DVD
The following commands create a DU CD or DVD containing packages SUNWfoo and SUNWbar.
# /usr/bin/pkg2du -r 5.10 -o my.iso SUNWfoo SUNWbar
# /usr/bin/cdrw -i my.iso
