Stacking 4 Dell EMC S4128T-ON Switches

Hi,

I have 4 S4128T-ON switches and planning to stack all of them. I'm new on using that switches and I'm looking for the stacking guidance.

Actually 1 of them using OS Version 10.5.4.4 Build 10.5.4.4.193 and the rest using OS Version 10.5.0.4 Build 10.5.0.4.638. It is still possible to stacking those switches with different OS Version?

Thanks,
