Pivotal career move, looking for advice

I have found myself in a conundrum.

I work at a large global corporation, I was hired in 2.5 years ago fresh out of school as a Manufacturing Engineer. I have a B.S. in Mechanical Engineering Technology. In parallel, I worked at various levels in the IT field throughout college (troubleshooting software/hardware and some programming).

For the past year I have helped launch a new PLM software across the corporation (developing processes and training other engineers). My engineering and IT background crossed paths and helped me excel in this particular role. I have an opportunity to move onto the 'systems' team full-time, and leave behind the 'functional' engineering role.

Has anyone made this move? Was it worth it? I think the question I am getting at is 'has anyone been completely satisfied and loved their role as an engineer but left to do something else anyway?'

I should say, I enjoy doing both jobs. If It were possible to work both jobs at 40-50 hr/week each I would. I enjoy working in the plant, working with my hands and having a direct positive impact on the people I support. I also enjoy the IT/systems side of things; impacting and improving how engineers and our customers interact with engineering data at a global scale as well as working with employees from all different corners of the globe.
