Problem with 404 after changing Route to products

[banan_44]

Hello,

I have changed Route to products in Traffic & SEO setting and now Google Search Console shows me a bunch of 404 error. I have expected that but only for a few URL, no all. Usually when I changed something in Traffic & SEO setting old address redirected me to the new one. In case of change in Route to products I have 404 for all old URLs. New are working fine. Is it possible to make a rule in htaccess that will redirect all old URLs to new URLs?

Previously my route to products was: domain.com/category-name/id-product-name

Now it is: domain.com/iid/product-name

There is a letter 'i' before 'id', short for item.
