Depending on you comfort level with Active Directory, it can be done in as little as 4-6 hours. The first time may be a little longer. I heard from people who are not well versed in servers taking a couple of days to complete the process. The steps are very well documented, so if you follow them exactly, you should not have a problem. The kit is a download from their site, so you can start reviewing the materials right away before you start the project. This method has been around for many years now, and is a very safe and predictable way to migrate SBS 2003 from one server to another. There is no better or fail safe way. I have been using it since 2005 and have done it about 30 times. The best $200 I ever spent!
