New Design – Pagebuilder migration?

Hello,

first of all I love the new design – It’s pretty amazing.
But I have one problem: I have designed most of the pages within my website using the Page-Builder inlcuded in versions prior to the redesign (for simplicity reasons).
Because of the new design not using the page builder, all of my pages are broken when I try to update the theme.
Is there some way to migrate pagebuilder-pages within the new design or do i have to rebuild every single site manually?

Any help is greatly appreciated – keep up the good work 😉
