My current site is on wordpress. We are currently designing a new wordpress site, with the same URLs. Our current approach is to go into the server, delete the current website files and ad the new website files. My current site has old urls which are 301 redirected to current urls. Here is my question.  In the current redesign process, do i need to create pages for old the 301 redirected urls so that we do not lose them in the launch of the new site? or is the 301 command currently existing outside of our server so this does not matter? Thank you in advance.
