I have created the new magento site and importing the data from the old site but I have the problem with the URLs. Old site URL starts from www.sitename.com but in my new site it starts from sitename.com without www. Now I am trying to add WWW in my magento site or remove the WWW from the old site through .htaccess file
but the problem is when I change the magento site bse URL to www.sitename.com it is giving server not found error
I have also used the htacess rule to remove the WWW from the old links?
