We are currently migrating from 5.2 ce t0 6.2EE. We have reasonable success migrating portlets over; however, I am having some issues with pages that are coming over with custom page css conflicting with the theme, particuraly booststrap. Our 5.2 theme column sizes are modified on the page css. Since bootstrap uses 12 columns , this has made it necessary to find each of these pages and remove the troublesome css. We are trying to have a minimum of post migration steps to accomplish. Is there a way I can search for conflicting css and remove it from all pages when migrating?
