If you do decide to get rid of dates in your permalink structure, you can add the following redirect to your .htaccess file (if you’re on Apache) to ensure that the old URL (/yyyy/mm/dd/%postname%/) points to the new one:
RedirectMatch 301 /d{4}/d{2}/d{2}/(.*) https://yoast.com/$1
For Nginx, you can use the following snippet in your site configuration:
location ~ /d{4}/d{2}/d{2}/(.*) {
rewrite ^(.*)$ https://yoast.com/$1 permanent;
}
