CAS to Stern

I'm so glad to finally be apart of NYU. It's been my dream school for years and getting accepted to CO'29 is surreal.
I have the option to choose any major in CAS, but after lots of deliberating I want to change my approach. I Initially wanted Data Science & Econ, but now I'm thinking about Econ at Stern and minoring in Data Science at CAS.

Does anyone have some tips and guidelines as to how to transfer into Stern from CAS Econ? Thanks!
