Errors in Backup

But now I've a problem to solve: 2 weekes ago I've made the backup of a website built with Betheme because I had to delete the domain and transfer to another domain and hosting. I've imported everything (files and database) on the new server, but half of my pages are empty.
I've noticed that the pages I've built with visual composer are ok, but not the pages I've built with Betheme panel.

while site migration, we always use 2 plugins and did never had any problems with content or settings migration. Those plugins are: WP Migrate DB and Mfn CB Migration Tool. Please use both tools for migration and everything should be ok.
Thanks!
Unfortunately, the old domain is expired, so I have the backup but not the online versione fo the website...How can I find my pages?
Could I send you the backup to find them?
