Moving Website to New Location – How Can I Keep Links or Quickly Update Links

Hi folks,

We’re new to this and created an updated version of our website in a temporary location with the plan to move it to the final destination when completed. In other words. we’re creating it at http://www.newsite.datades.com but want it to ultimately be at http://www.datades.com. About half way through the creation of the site, we’ve realized that all the links we’ve created point to pages with the newsite.datades.com address. Is there an automated way to update all these links when or before we upload the files to datades.com?

Hopeful but doubtful…
Sandy
