Since I don’t have access on the database, please try this one. Go to your Enfold database via cpanel > phpmyadmin. Look for the wp_layerslider table. Select all the slides then export it using XML format. Go to the new installation then import the wp_layerslider xml file. Make sure that all assets like images are in the proper folders and with the proper file name.
Note: You should export the slides inside the wp_layerslider not the wp_layerslider table.
