If you’re moving your blog or website from one domain to another, you you’ll want to retain your search result links and PageRank. Also, if people are using the old links, you want to redirect them to the new domain.
Enter the 301 Redirect.
Here’s a very simple redirect…just replace the contents of the .htaccess file in the root of your ‘SOURCE’ site with this (replace with your ‘TARGET’ domain)
RewriteRule (.*) http://targetdomain.com/blogs/$1 [R=301,L]
You’ll need to keep your old site up for at least 30-40 days.
