how to upgrade NPM and move to new server?

I've been tasked with upgrading NPM from 9.1 SP5 to 10 and moving it to a new server, which will have the same name and IP address as the original server (in order to continue using existing firewall rules).

Is there a 'best practices' way to do this?  Is all the information for NPM found in the SQL database?

thanks,

Tom
