There are probably many different ways of doing it. When I made the transition I organised mine by position, AEA SM, AEA ASM, SM, ASM, then PA. I also put when I joined Equity (month/year) in my special skills section for a while. I felt that it helped explain why I had my shows separated the way I did. It really comes down to what works for your credits. Put it together in a way that makes sense to you and then have someone look it over. Good luck and welcome to the Union!
