Thank you Bruce and Tom.
I ran the delete_old_cluster.sh script, and it did the job. Appreciate all your work and timely response. That was my bad, I did not want to remove the 9.4 directories until I validate the database upgrade fully, so made some wrong assumptions about hard link behavior.
Thanks again,
Ganesh

Uh, after the upgrade, the output say:
Running this script will delete the old cluster's data files:
./delete_old_cluster.sh
That script is designed to do this cleanup.
