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
