Moving from one p.o.s. platform to another p.o.s. platform, there should be some transferable skills and principles. Of course, you'll need to re-certify with SAP. Whether it's worthwhile depends on your views on the market.For example, if you believe that with the introduction of Fusion companies will take the opportunity to switch to SAP, then you could position yourself well as someone who understands both sides of the transition. If your company has a strong Fusion team and P.O.V. then you might be better to wangle yourself a position with them.
