Export from joomshopping 4.6.1 to 4.12.3

Export/import from joomshopping 4.6.1 to 4.12.3

Hello, i m doing a new version of mu webshop, now i m working on joomla 3.3.4 with joomshopping 4.6.1, i ve decide to make a new website with new joomla 3.5 new template e new version of joomshopping 4.12.3
But
I need to export all my category, subcategories, articles an attributes and " images" from old webshop to new webshop

What addon i can use?
Can i use the standard import/ export than i find on installation of joomshopping 4.12.3 or i must buy something?
Another thing, now my site is single language but the new will be dual language, can give me some problem?

Thanks
