I used two Regex redirects to bulk redirect my product tags and product listings from my Woocommerce store to my new Shopify domain. Then I tested one-by-one each Woocommerce product link, Woocommerce product category and Woocommerce product tag.
Example:
https://artsandbricks.com/product/(.+)
redirects to
https://store.barkhurstcreative.com/p...
In this expression, the (.+) matches the changing part in the source URL. Adding the parenthesis makes the changing part in the source URL a "capture group." The (.+) will match any number of any characters, so it should catch all the old links. The second part of the redirect uses $1. The $1 token will match whatever is in the capture group in the old URLs, so the $1 to adds the matched part to the new redirected URL.
