So excited to see Quest making migration possible directly from SPS 2003 to 2010. I know Microsoft was relying on third parties for this. Alex Kirilov and team now have a pre release Technical Preview version. We’ve chatted about this and actually was one of the main topics of my discussions in St Petersburg. I hope it’s everything you wanted. Check it out! Tested with both SharePoint 2010 Beta & RC
