Rather than trying to link things like this is it possible to just have the record id there in the data from now on? On the website make sure the record id is listed for the product in the first place so that the data can be properly related and you don't even have to do this. If you go this route and do text matching it is potentially inaccurate unless the product names are similar to skus. If they are, I think you could also just use the product name as your record id instead of record id itself but you would need to test that.
