Transferring from Buffalo possible?

I applied to the SOM at both Buffalo and bing. I was admitted to Buffalo SOM with a good scholarship and rejected from bing SOM (accepted at harpur)

I’ve been reading this sub and it seems practically impossible to switch from harpur to SOM. What do you suggest I do? If I spend a year at buffalo SOM and then transfer to Binghamton SOM - would that be a viable option? Will it be harder transferring from harpur to SOM?
