Is it possible to transfer a site created with wix editor to editor x?

directly or indirectly

Editor X does not exist anymore. There is no direct way to transfer a site to the Studio Editor. The only way is to create from scratch. You can export and import CMS data and a few other items from the backend.

So, are there any extra features that editor x offers? For example, a site created with editor x loads faster, etc.

There is no editor x
