Migration to a new domain of pages built with Elementor

Hello. My welcome-page is designed with Site-Origin-Builder. I duplicated this blog to get a test-configuration in the same hosting, and I manually did this migration without any plugin – duplicator, all in one migration – (copy of the files, database, update of wp-config.org and four SQL requests in the database to update the link). Everything seems OK except the welcome page that could not be correctly transferred: the blocks (or rows) were lost.
I would like to try Elementor with my test-blog, but what is the status of Elementor regarding a possible migration of a blog ? Regards

The page I need help with: [log in to see the link]
