Thank you all for responding. I do not think immigration at Dubai Airport is needed, just have to go to the appropriate Transfer Desk for the boarding cards for the connecting flight. My point is, Cathay maintained a minimum connection time at Dubai of 90 minutes between flight. Can I through check-in a baggage with a connection time of 1 hr 25 minutes? Since the next flight out of Dubai for the inbound portion is 2.35 am next morning, I would rather not waiting 6 hrs for another 45 minutes flight.
