Thanks for your reply.

If i understood properly, you are advising me to create a new list with the new list owner name and refer that list in all my lists. Am i right?  I have one more question here.  If i have to refer my new list(with the new list owner) in all my lists,  do i have to edit all lists individually or how to do that?

Please explain me.
