I moved a issue ticket from Project A to Project B because i need the issue to undergo few status in Project B.Once all this status are done i want the issue to auto assign to the user who has moved the ticket. Can we achieve this.

Not directly.  The sticking point for me is trapping the user who does the move when they do it - once you've stored that, assigning back to it on closing the issue should not be hard with Automation or the Script Runner.

On server, I know I can write a listener with the Script Runner to catch the move event and update.  I've not tried it with Cloud Script Runner.
