Sounds similar to what happened to my team. In our case, it was "only" two years of hard-won domain expertise, but we were also "trained" by the original founders (who had left at some point after the acquisition). The new team had zero domain knowledge and while we tried to hand everything over as well as we could, it seemed like a lost cause to me. A couple of months later, we found out our old company ended up buying the competition.
