I wanna move product category order from Magento 2 to Magento 1. 

what is the best way for this? I create export from product and import to Magento 1 by default tools on manage but I get some error like 

> product type does not match and....

 so that does not work.

What is **difference between M1 DB and M2 DB** and it impossible to use M2 DB for M1?
Or maybe we move some table between two databases?
