Hello,
You can export/import pages using default WP exporter: Tools > Export/Import > pages. But keep in mind that images used on these pages won’t be exported.
Also, you can use third-party plugins, for example, WP All Export plugin.
These settings are default WP settings and are not related to our theme. Our theme does not have any additional options to import/export site content. Our theme has options only to import/export theme options and header built using header builder.
Regards
