In the Mogstation you'll need to use the option Free PS3 -> PS4 upgrade. That will change your PS3 license to PS4 one there. And yes - it will copy over all your "local" settings which includeds gear sets, macros and cross bar settings. The only thing which is not copied (on purpose) is the HUD settings which is due to the differrent resolution on both systems. Also remeber in PS4 system settings to change the Display area to cover the whole screen as by default it has a thick "border" around to which you'd be otherwise unable to move the HUD elements in game.
