If not in the same terminal, a bit more of a hassle. After clearing immigration and customs you will need to go outside to catch a between-terminal bus. It's a bit of a hassle if you have much luggage to load onto the bus, as the space can be limited. That bus ride takes about 5-10 minutes. As I recall, they depart at 10-minute intervals.
