Hi, Not meta tags.  If no other way, You should do it with PHP  header() function.

<code>header("HTTP/1.1 301 Moved Permanently"); header("Location: /somelocation");</code>

But you need to add some conditions to determine if the page should be redirected. For example to redirect /example.html  to https://www.new-domain.com/example   you need to write something like:

if (isset($_SERVER['REQUEST_URI']) && parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH) == '/example.html')

{header('HTTP/1.1 301 Moved Permanently');header('Location: https://www.new-domain.com/example');exit();}

It can be a lot of code, if you need to redirect many pages. In this case, You can try to use PHP 301 Redirect Generator -  https://www.301-redirect.online/php-header-location-generator

There  is no difference between "Redirect 301", "Redirect permanent" and  "RedirectPermanent". It is clear from mod Alias documentation:

"This directive makes the client know that the Redirect is permanent (status 301). Exactly equivalent to Redirect permanent."   "permanent - Returns a permanent redirect status (301) indicating that the resource has moved permanently."

But, these directives are really confusing, because they are not page to page, but directory to directory.  For example:

Redirect 301 /a-very-old-post/ http://yoursite.com/a-very-new-post/

Surprisingly, it will redirect all old subpages to new subpages. In particular it will redirect  /a-very-old-post/page1 to /a-very-new-post/page1  Therefore better to use RedirectMatch or RewriteCond+RewriteRule for page by page redirections and for redirections with query strings.
