Do I need to point the config files to the same sql? and do I need to do anything else?
It is not that simple
I am looking to have multiple domains using different zen cart templates but would like them all to link to the same SQL and admin. Is this possible.
There is a 3rd party module - "multi-site" that many have used with success

I intend to purchase a number of templates that I like from template monster for 5 seperate domain names each being a .com, but I want them all to use the same SQL so that I can keep a track of all sales and stock through the one admin.
Do yourself a favor and search this forum for them and take note of all the issues and possible lost functionality with their templates
Compounded as you will be using several and they will most likely be written by seperate individuals and they have no standard so each will present a different set of issues
