How to update Item Variants if the item is already created and have transactions?

Hi,

I’m just trying to find some guidance and help about item variant. Because I have a problem with linking variants in the item that is already created and have transactions. Since I am renaming and reorganizing the Item, I need to create an Item Template and with that, I want to link the variant of in the template and the variant attributes.

Right now, I can’t add or update the variant tab. I needed some help. Thanks in advance
