we are seeking for advice about changing existing NAV VAR. We are not satisfied with current NAV partner for multiple reasons. We would like to replace them with another one, or at least work with another partner on development of new functionality.
Problem is that we bought from current partner their add-on, which is very important for our work. We are not sure if new partner can get license to maintain this add-on. It they can not get license does it mean that we are forced to do business with existing VAR? We would be satisfied even if existing VAR only maintains add-on and new partner is responsible for other stuff. But if existing one cancel us support for add-on we are in deep trouble.
Do you have some experience in similar situations and what do you suggest?
