I search how to configure a custom theme in Magento Enterprise ver. 1.12.0.2 without doing a copy of all the base/default files.
The only way I can make it is to create my_theme folder in /var/www/magento/app/design/frontend/enterprise/my_theme and then in system>configuration>design to let enterprise as "Current Package Name" and my_theme as "default" in "themes". But I'm afraid it's not the ideal way in case of upgrading Magento.
Is anyone have an idea ?
Thanks
