We are building a new site on a new server and plan to transfer our current domain name to the new site/server. Some of the pages in our current site will remain on the current server and in order to continue to access those pages we have created a subdomain, which points to the current server. Do I create 301 redirects from the new server to those pages with the new subdomain name? Even though those pages won't ever have existed on the new server?
Currently I have www.example.com/page
which will continue as subdomain.example.com/page
when we make the switch over. Do I create a 301 redirect on the new server: /page -> subdomain.example.com/page
I don't know if it makes a difference but the new server is linux and will be hosting drupal and the old server is windows 2012.
