Updated from 3.0.4 and lost many styles/settings

Hi there,

I just inherited managing a site that was on old WordPress, Enfold 3.04, old PHP. I managed to get the site onto a new host staging area, purchased a new Enfold license, downloaded latest Enfold and installed and switched themes, updated WordPress to latest, updated PHP to 7.3, copied over custom CSS from old Enfold in the Customizer, and checked the custom.css file in the old Enfold and there was no additional CSS. I also exported Theme settings from old Enfold and imported them into new Enfold.

Everything is working and the site looks relatively similar, but background images and styling are missing. Is there any way that I can recover them from the old site, or do I need to rebuild all these settings and styles from scratch.

Thank you,
Erik
