For Microsoft asking users to visit their support forums there are a number of threads going unanswered here with very legitimate and critical questions being asked by customers needing this information for planning their AD migrations that only Microsoft or very experienced 2008 admins can answer.Would be nice to see Microsoft stepping up here.

Microsoft forums and newsgroups rely on the volunteer work of hundreds of people like you and me. We're answering questions as fast as possible and it's for free. Most people answering questions are not employed by Microsoft. If anyone needs help with planning a migration oranything else that's too difficultthere's always the possibility to open a case with Microsoft, or get a consultant to help out. The lack of information in many questions also make it impossible to answer and I don't think a successful domain migration is planned in a forum unfortunately. My 2 cents.
