Upgrade From 7.1 To Latest

Hi all,

Our current configuration is Webfilter 7.1 loaded on a Windows Server 2003 R2 box with the database residing on a Windows 2000 Advanced Server running SQL Server 2000.

I would like to get upgraded to the latest Webfilter version (7.8.3?).  I have a Windows Server 2008 R2 machine ready for the installation and a Windows Server 2008 R2 machine with SQL Sqerver 2008 R2 ready for the database.

So how do I get from point A to point B?

Thanks.
