In my not-so-expert opinion, the overwhelming majority of your questions appear to have perfectly valid answers, with numerous upvotes by other community members.
Just as a random example, the answer provided by meklarian to this question is about as good as you're going to get. I don't have anything more to add, or I'd have posted an answer of my own.
And questions like this one are discussion-type questions. I'm sort of surprised that one hasn't been closed already. The answer, of course, is to simply try to migrate the project and fix the errors you get. No one can give you a laundry list of all the things that might possibly go wrong. That wouldn't really be useful to anyone.
I'm not sure what other questions you think have received inadequate answers. The general rule if you're not getting good answers to your questions is to go back and edit your questions to improve them. Provide more details, try to give a better explanation of what your problem is, and add whatever new information you can think of. This also "bumps" the question back to the top of the list, so that more people will see it again. It may sound harsh, but the Stack Overflow community is pretty awesome, and usually when you aren't getting good answers, it's because you're not asking good questions.
On the other hand, I wouldn't worry too much about your accept rate. The only users whose accept rate I ever comment about are those with a 0% accept rate that are obviously new to the site, and might not even know about accepting answers. You've obviously figured out how to do that, so it's your prerogative whether you want to accept them or not. In my experience, there's little to be lost in not receiving answers from the people who, as a matter of policy, refuse to answer questions from users with a low accept rate.
