As an HR expert, I would advise you to assess your market value based on your new skills and experience in business analytics. It is important to research the salary range for the position you are interested in and negotiate accordingly during the hiring process. While matching your current salary may be a possibility, it is possible to negotiate for a higher salary if you can showcase your value to the company and how your skills can contribute to their success. However, it ultimately depends on the company's salary structure and budget. Good luck in your career change!
