need to rebuild page in a different page builder

Hi,
We recently changed the theme system for aficreditsolutions.com from X to the Loinstar Credit Repair Theme. This page was built in X's cornerstone page builder:
https://aficreditsolutions.com/the-hub/

We need to rebuild it in a different page builder (considering site origon). Will it need to be fully rebuilt or can the existing layout/images/text be imported into another page builder?
