I depends on the class of the Catalog Item!
As not all of the sc_cat_item classes has the related field to the model classes.
I usually create the model and from the model create the Cat Item then they are liked automatically, and allso end up in the correct sc_Cat_item class, for hardware models pc_product_cat_item and for software pc_software_cat_item, there are others as well.
So if you are in the wrong Cat Item class then you are in for a treat.
I have never tried to move an item, or any record at all, between classes.
I have only recreated them correctly.
And then you have a connection between model and item.
If they are in the correct classes then its just a question of updating the fields.
But best is do do it in the correct order.
Model then Item 🙂
