It was a lateral move within the same company, so my compensation is identical to what it was before. Honestly I credit my manager and the company in general for allowing me to make the move. My manager was extremely supportive when I expressed interest in product management and was quick to throw my name into the hat when an internal job opening popped up. I think it helps that I work for an extremely large company. I doubt I would have been able to make the switch if I was still working at a startup.
