yes, to avoid upgrade problems I faced in past, I prefer to do
clean install from CD. I have / partition and /home partition
I have formatted / partition but /home is from 9.04 install
at that time /home was also formatted and backup was restored.
that was on 29 sep 2009.

I appreciate your kind efforts to help me out.

Thanks and best regards.
