Regarding to assign categories

Hello To all

 

My site is working fine with „Deutch“. Now am going to make it „englisch“ also. I have upto 750  products under „deutch“ category in various directory.I cannot edit and assign category for every product for the enlisch directory  I need to make the same structure under enlgisch directory in order to display in englisch language. Can i make a duplicate and rename the directory? I tried duplicate category and rename it. Is there any problem cause with production site if i make a duplicate category?

 

Thankin in advance
