While PM role means different things in different companies (even between teams in bigger companies) let me tell you what you will miss the most transitioning over from Eng: You can no longer hit a button to compile your work and see the output (even if it is a small part of the whole). As a PM from initial proposal to outcome is typically 6 months or more. And you fill that time with negotiation, communication and a whole lot of politics (the good and bad sides). Then you may see the outcome you had envisioned (but no guarantees). It is just, different. Be prepared.
