@bram1974 yes it would be extremely smooth to migrate to Cardinal, weโve made vast improvements to the page builder, and the only thing that should need to be changed are the base shortcodes. This should easily be updated with a search & replace plugin.
The plan is to provide a set of search & replace statements, and then it will be a simple swap that only takes a couple of minutes.
The theme options panel is different, but post types, meta, and most of the colours etc will also transfer across smoothly.
