I am updating an old drupal 7 site and many of the old nodes now have newer counter parts with new nodes. Since alot of my old nodes have already been spider-ed, I want to do a 301 redirect to the new nodes. I'm currently doing it manually by deleting the old node and then copying the URL alias into the redirect module and redirect it to the new node path. Is there a easier way to do this if I have 1000 nodes that need redirection?
Redirect Module + Path redirect import Module
The module Redirect has great options, one of which creates redirects when you rename a page and hence change an alias.
The module Path redirect import works with Redirect and allows you to upload a CSV of redirects (or use Drush), it even checks if a page you are redirecting to exists.
