Ask HN: Adapting to corporate culture after being acquired

After my last post about being acquired, big company and us are moving forward into the process. I've become aware that their culture is far more corporate that what I'm used to (having worked for myself, contracting, or small companies). I'd love to hear any stories/advice on adapting to corporate culture while taking on the process of integrating your product/business into the acquiring company.
