I couldn't resist to share with you this great screencast about the new MS CRM Data Migration Manager (DMM) available at Channel 9. If it works like John O'Donnell shows at the video it will rock for sure!
However... I still need to make it work on my development environment. I'm geting this "Failed to determine the SQL data root path for CRM instance." error. I'm not the only one because there is a thread at Dynamics forums about it.
