You are 46 years old and I think you have hardly any chances of changing your field of job. Moksha and the rebirth if at all there is one cannot be predicted using astrology. You can contact some wayside astrologers to get an answer to your questions if you are insistent.

Perhaps it will be better if you read through my book given in my profile on this site. Astrology is like road signs are to a motorist in your travel from birth to death which will help you to forewarn you about impending dangers or difficulties on your path ahead.
