Breastfeeding to exclusivity pumping?

Is there a proper way to move from EBF to exclusivity pumping?

My baby just seems to be happier I am happier and my toddler is happier this way, my two month old seems to be drinking 3oz every 3 hours and that’s how much I am able to pump each session combined.

Anyone else have tips that were able/ moved to this.

Thanks!
