How Do I Create A Meta Refresh Redirect In Adobe DreamWeaver

Google Developers recommends allowing old URLs to go 404 so they can drop from Search Engine Results Pages (SERPs). 

When that's not practical, a permanent Rewrite on the server will seamlessly redirect users to new URL automatically.  No browser activity required.  Using 301 in an .htaccess file enables you to redirect users from an old page to a new page without having to keep the old page on your server.  If your hosting plan has WHM or C-panel, you can do this by logging in to your server's admin panel. 

Or you can create/edit the server's .htaccess file manually in Dreamweaver and upload to your server's root folder.

Some 301 Rewrite examples for .htaccess file.

## REMOVE WWW FROM URLS ##
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.
RewriteRule ^(.*)$ http://example.com/$1 [R=301,L]

## REWRITING HTTP TO SECURE HTTPS ##
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

## REDIRECTING NON-EXISTING LINKS TO INDEX PAGE ##
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.html$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.html [L]
</IfModule>
