Upgrading from

Hi there, we have a very old website running on version I know it´s not easy, but are there any options to upgrade to version 9?
Or if not, how can we transfer as much as possible (content and design) to a brand new installation?

There are no upgrade options, but you can use the Migration Tool to move content. Unfortunately you will probably have to rebuild the theme for the new ConcreteCMS version.
