.htaccess 301 redirection

Hallo,

I’m putting together some multisites I had into one big multisite, the thing is that I want to make 301 redirections. For example:

From: https://ritort.net
To: https://ritort.org/organs-de-govern/fundador/entorn/

I tried this .htaccess configuration:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^ritort.net$ [OR]
RewriteCond %{HTTP_HOST} ^www.ritort.net$
RewriteRule ^/$ https://ritort.org/finalitats/$1 [R=301,L]

RewriteBase /
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(wp-(content|admin|includes).*) $1 [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(.*\.php)$ $1 [L]
RewriteRule . index.php [L]

But it didn’t work. Any idea?

Many thanks!
