Hey Centropolis 
!
Great to see you here and thank’ s for asking!
CMS and Ecommerce content (databases) aren’t exported. Collection lists will show the empty state. Collection pages will also not show any content that’s bound to Collection fields as well.
It’s probably possible to reinsert the cms entries manually, I’ve never worked with the exportet .csv from cms collections though!
— How are they structured?
— Are images stored as blobs?
It’s probably quit tedious, I’m willing to help you here
