I'm in the process of downgrade from Enterprise 1.14 to Community. I have seen this post http://www.yanted.com/2014/02/21/downgrading-magento-enterprise-to-community/
What I want to do is do a fresh install of Magento Community (latest version) and use my old database from enterprise but fix it to can use it with community.
So, should I delete all the tables that start with the prefix enterprise? And also do what says in the post
DELETE FROM eav_attribute WHERE source_model LIKE 'enterprise_%';
DELETE FROM eav_attribute WHERE backend_model LIKE 'enterprise_%';
DELETE FROM eav_attribute WHERE attribute_code IN ('gift_wrapping_available', 'gift_wrapping_price');
I want to do it the cleanest but need to preserve the data.
