Regex Expression for Permalink Change

Hello,
Without knowing I used for my articles the following permalink structure
/%year%/%monthnum%/%day%/%postname%/
Now I want to change it just to /%postname%/
I know that by matching patterns, WordPress can automatically redirect those date -name permalinks, to the updated post-name structure.
But I want to be sure that I won’t have any major 404’s errors.
I am using the redirection plugin. I found the following expression that suits my needs:

Source: ^/\d{4}/\d{2}/\d{2}/(.*)
Target: /$1/

How can I make it to redirect site wide, for every article in my blog?
Please, I would be grateful for any suggestion!
Kindest regards,
Fil
