Congratulations! You've decided to go from being a specialist to being special.

The biggest advantage of your move is that as you dig into software development you will be equipped with two advantages:

Dual skills set plus a unified understanding of two different fields you might even be able to create new knowledge.

My advice would be to develop something in the field you already know, something that made your life more cumbersome but that technology could solve.

That way you will be using your intuition from a field you know to solve a specific problem while learning a new field.
