Hello Everybody: I?m a user of the product ISA Server 2000. In 2001 year I bought your book and now I?m using it to understand and supporting me about the product? It is the product that has a lot of documentation ? thanks to you and others, there is a lot of information. So I?ll go to buy your ISA Server 2004 book, because I want to migrate. I?m looking information about how to move the configuration of my ISA Server 2000 to a different computer with the same version of ISA but with other hostname, So, after do that I want to run the upgrade to ISA Server 2004. What can you recommend me to preserve my configuration and to have a point of return..? I don?t want to move by hand rule per rule. (I?m sorry for my bad english) Thank You, Leo Ramos Guatemala.
