Hey Rami Pelles,
You might be able to run Elementor, but we don’t have any official support for it since the theme comes with its own Layout Builder. If you are going to use Enfold then I would recommend that you use the built in editor to avoid conflicts with a third party layout builder.
It should be no different to migrate a site using Enfold than a site using any other theme.
Best regards,
Rikard
