Massive links convertion from 302 to 301

Question

I have a WordPress website with different 302 redirects, I would like to change these links from 302 redirects to 301.

I have more or less 160 links so I need to find a massive way to do it. Is it possible to do?

I could use this

# BEGIN 301 Redirects
Redirect 301 /wp/old-page/ http://www.testdomain.com/wp/new-page/
# END 301 Redirects

But in this case, I should convert all the links one by one which is not really quick.

This is my .htaccess file:

# BEGIN WpFastestCache
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Insert this generic rule just above # Start WPFC Exclude line:

RewriteRule ^/?(seal-manufacturing/[\w-]+/)(.+)$ /$1 [L,NE,R=301,NC]
