I have a website (A) and I copy it to another (B), I export products using CSV. from site A to site B. The Import process copies the same amount of products, but the category and subcategory are different, varying the number of items in the categories and some subcategories do not exist.
All categories are imported without a photo, I need to resolve this, as it is not reliable back up and I can not be putting Shot and checking one by one the categories so that they are equal. The pictures of products are imported correctly.
In short: I need to export all site A to site B, keeping products, categories, subcategories and photos.
I leave some captures from Site A (original) and Site B (copy)
Site A:

Site B:

Thanks a lot.
Someone from Ecwid can give me orientation. Thanks!
