If you have a project running with TemplaVoila and want to get rid of it, we have a solution for you: We built a TemplaVoila Converter, which converts the whole content from Flexform to TCA. It creates the necessary fields, contentelements and backend layouts. It respects translations, references, nested content, contentcolumns and much more.
