Hello, rajeshkathar
If you can not use LVM, this will be hard, because you can make snapshot somewhere.
But if you use LVM, you have just format your “root” partition, and then install your new release RHEL 7!!!
I recommend you, to use LVM or GPARTED, after this!
Do not try to upgrade system V with system D, you can not do this!!! :smiley: ok.
Good luck my friend and best regards.
