Your assumption is that mass pogroms were possible, such attempts would've lead to massive revolt and unification of all hindu ally's and perhaps Mughals losing power. Having said that in Afghanistan, Pakistan, Kashmir, Iran ( which was Zorastrian ), state discrimination and oppression of Zorastrians were used.
Again that doesn't mean all Indians converted through sword, but discrimination was a tool, jizya, and even extreme oppression. India has more Zorastrian than modern day Iran, more Sikhs, Jains and even countless Tribal religions. All other neighbouring countries which had Islamic rules have either a dwindling population, or nothing left.
