We have a WordPress implementation "MultiSite" hosting 4 sites and the Database is running on MySQL. We would like to have two servers, one for DEV/TEST and one for PROD. The purpose for this is to add a layer between our developers and what is in Production. The question I have is:
What are our options for taking whats in DEV/TEST and publishing them from a file and database level to Production? Any version control software that works in that manner with WP?
