Having gone the other way, from Microsoft to entrepreneurship, I would say you are better positioned for success. For the most part your skill sets will transfer over to product management in a large company fairly easily. Some things are different though. You will typically be responsible for either part of a product or one product in a portfolio. As such your product or feature's future depends not just on how it is doing in the marketplace, but how it does relative to other products and features in the the portfolio. So you need to work with your managers to evangelize and promote the product within the larger organization as well. You'll have be able to justify its existence, very robustly with a lot of data. Much of the mid-level product managers function within a large company comprises of this activity. This may seem wasteful to you, coming from a startup, where the verdict of the market was everything, but this is how large companies determine how resources are allocated. Eventually the market will determine the future of the product, but for many product managers in large companies, that success or failure will not occur in the duration of their tenure. So one thing you need to focus on a lot is networking with the internal power structures of the company to build support for your self and your team. You have a huge advantage in this respect as an acquisition. They have paid good money to bring your team in, so there is significant awareness of who you are. If you are careful, and politically savvy you can leverage that awareness, and initial goodwill into strong long term support for your team and product.
