Hi dadgar,

Thanks for sharing details.

So, it is easy to do.

1. Theme Settings

Navigate to Theme Settings > Import / Export / Reset and export all theme settings, then you can import to new site.

2. Content / design

You can create a dev site and import any template there, then with the help of the import functionality of Elementor you can copy the Home page or some specific blocks and move it to the main website, more detail is here: https://elementor.com/help/template-library/
