I'm about to do both and upgrade to latest version, and a server change at the same time. On the new server I will also be making changes to the products. New prices and things like that. My question is about making the move. I've installed latest version on new server. Should I set-up the new products billing, emails and other items now? Or, do I back up the database first on old site (with older version and older settings / products) and import it to new version / new server, then make all product changes? Jimmy
