Hello,
Thanks for contacting us.
It is recommended to run import on a fresh WordPress installation. For this you can use WordPress Database Reset plugin https://wordpress.org/plugins/wordpress-database-reset/ The plugin can be used to remove all the existing content and install a new version from scratch.
I prefer Elementor better than WPBakery and 70% of our customers use the Elementor and only 30% use WPbakery. Elementor has more content elements, more responsive options, and works smoothly. I like that.
Regards
