Help upgrading to 9.1 from 8.1

Hello,

My company is currently running Shavlik 8.1 on a Window 2003 server with SQL 2008 R2.  It no longer will download definitions and we can not even patch with the patches that it currently knows about.  I know that I have to install a new OS.  When I install Windows 2008, do I just install Shavlik 9.1 and then install the Database in SQL 2008 (on the new server) and run the Setup database tool and it will migrate it to the 9.1 SQL database structure?   The only thing that is in there that I can't lose is the patch groups.

Any help would be greatly appreciated.
