I have a lot of products which currently have url structure like this:

https://www.mywebsite.com/product-name1

or

https://www.mywebsite.com/Product-name1 / capital P

I have rebuilded my website using WooCommerce and the default url structure looks like this:

https://www.mywebsite.com/product/product-name1

What would be the best approach to handle and append /product/ in each of the product urls and use the 301 redirect on them?

I have tried this:

RewriteEngine On
RewriteBase /

# Redirect old OpenCart URLs to new WordPress URLs
RewriteRule ^(.*)$ /product/$1 [R=301,L,NC]

And I believe somewhat it worked but it messed up some urls and products started loading without images and also /product/ was appended in my url when I browse the website and the admin section.
