Prepping for Sleep Training - Snoo Help

Baby is almost to the 16 week mark and we’re looking to start sleep training sometime in the next 2-6 weeks in hopes that we can get this done before I head back to work and daycare starts (baby still will only contact nap currently).

We have a Snoo and did the 6 month rental option. Should we start activating the weaning mode now to help the transition or is that not really necessary? And when we do start sleep training, do we start it in the Snoo with the motion off or is it best to start by having her in her crib/room?
