Shifting from Sales to Dynamics function consultant


I have nearly 8 years of experience in Sales and Channel development and planning to shift to IT by doing Dynamics AX (Retail or Supply Chain).

I am confused it this professional change will be a good decision for me or not because I need to start from scratch with less salary. I have also dont Executive MBA from Manchester Business School - UK (2009-2012).
