How can I select a replacement product ?

Hi,

I would like to replace a product without deleting the description that is online in my store.

So instead of deleting the description, I would like to import the product and keep the same info being online.

It’s for the Seo, I don’t want to delete a product already online. I want to leave the product online, but replace it with a new one.

Thanks in advance.

Sincerely
