Hey Murray, for the 301 redirect, I just replaced the contents of the old site’s .htaccess file with the code below:

# BEGIN WordPress

RewriteEngine On
RewriteCond %{HTTP_HOST} ^thebacklight.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.thebacklight.com$
RewriteRule ^(.*)$ http://blog.osmosio.com/$1 [R=301,L]

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress

You’ll need to change the 3 URLs there. The first two are the same, just with and without the “www” part, and the third URL is the address you want to redirect everything to.
