Reversing a stepper motor wiring help

Hi simple question probably easy for you guys, I need to reverse my stepper motor direction and I know its a matter of swapping wires around but I'm not sure which ones , so some help would be gratefully appreciated

My wiring set up is the one on the right below 21 kg

Attachment 25249

Just swap one coil pair, say A- and A+.
Best Regards

Yes, you can just reverse one pair of windings, you can also do it in software by inverting the the dir pulse.
