Category ID

Hello All.

I’m new with Shopware and heard alot of good comments on it. So I would like to try this.

My supplier has sent me a .csv file with all the information I need to setup my shop, but I am getting stuck on the category ID.

They use Shopware and I would like to have the same Category ID’s as they use, is this possible? For example :

Categories ID : 4068|5849|6238|6251|6252|30182|40182|50182|60182|70182

Is this possible of must I create my own categories?

Also an other question, will the products name that is now all in German, translate automaticly to Dutch or English? Or must I use an plugin for it?

Thank you!
