Export&Import clients between Hikashop's sites

First of all, thanks a lot for your wanderful application.

I need to know how to export user/clients from one HikaShop instalation (version Starter 1.5.5) to another to another (same version), specially personal information, usernames and keys.

I haven's see any option in the component configuration (only for products).

Would be enough using an extension like Userport ? Which databese tables should I export and import?

Thanks in advance for your help.

You will indeed have to use a 3rd party extension for that.

But for the addresses of the users, that is handled by HikaShop and stored in the hikashop_address table which is linked to the user entry in the jos_users table via the hikashop_user table. So you will have to export/import these two tables two.
