By bus
As of today (Feb 7, 2032) the only way was by a rather dirty transit bus. Give yourself a solid 30 minutes between terminals.
There's normally a driverless transit system available. Unfortunately its been denied for renovation for several years. There is a bus that will take you from Terminal 3 to Terminal 5, it's not the fastest thing around but will save you a very long walk.
