Migrating to Microsoft Exchange 2000

I am in the middle of a large Windows NT 4.0/Exchange 5.5 to Windows 2000/Exchange 2000 migration where the overall design was done by others. Our implementation team has a lot of experience with Windows and Exchange, but not with Exchange 5.5 to Exchange 2000 migrations. The proposed Exchange 2000 design left us with a lot of questions and the designers were not too forthcoming with answers. This book answered our questions and more.This is not a book for beginners. In the introduction the author has a section on "Who should buy this book?" - he assumes familiarity with Windows NT, Exchange and Active Directory. You'll need all that familiarity and more to make use of this book. But if you meet the background requirements, and are currently evaluating, designing or implementing an Exchange 5.5 to Exchange 2000 migration, you should read this book.I also like the author's "case study" approach to presenting the information. A subject this highly technical and specialized could be almost unreadable. By using a fictional company to illustrate an actual migration, the author has given the book a narrative flow which makes it much more readable. I hope the publishers add more books to the "Gearhead Press" series.
