Two Hue gateways working SBS

I have More than 60pcs Hue lights at my house. Now to add more lamps and luminaires
I am looking help how to use the multiple bridges function. Right now I have motion sensor paired to my GW2 and would like to control light that has been connected to the GW1. Should this be possible or am I doing it wrong? Let me know if this should be done only so that GW1 goods are controlling gateway1 products and GW2 with only GW2 products because this kinda sounds oldschool…
