I just recently took over a site that is using an older version of Zen Cart. I would like to update to the most recent version but due to the previous webmaster doing some core changes I think my best bet would be to do a fresh install and slowly transfer parts of the site over on my test server. I have a few concerns about the databases. I basically just want to know if the customer database is compatable. I would hate to loose all customer accounts. I'm not so worried about transaction history or anything as we have paper copies of everything here.
If someone could ease my worries and let me know what steps I should take that'd be greatly appreciated. I am installing the latest version on my test server today. Thanks.
Re: Upgrade question
The database-upgrade step in the zc_install/index.php process will bring forward all your customer and order history, upgrading the database structure to match the new setup.
Naturally, you would want to do a "test upgrade" in a safe place before doing the "live" site.
