: Changing CMS and URLs I'm migrating a busy web-shop (10'000 IPs/day) to OpenCart, manually copying all the products, tags, descriptions and architecture. The old website was not built following

@Jamie184

Just to add to Yhorian's answer... it's relatively trivial to implement such a redirect. For example, if using Apache's mod_rewrite in .htaccess then it's essentially a one-liner. Something like:

RewriteEngine On
RewriteRule ^([w-]+)-p/(.*) // [R=301,L]


This specifically works on a URL of the form /Some-Category-p/Product-Name.htm. The regex might need to be adjusted depending on the URL structure.

The ([w-]+) part captures "Some-Category" and (.*) captures "Product-Name.htm" (everything after the first slash). These are then available in the and backreferences respectively, which is reassembled in the substitution (//).

Take each of the URLs and add them as 301 (permanent) redirects to the new URLs.

So accessing Some-Category-p/Product-Name.htm redirects to /Some-Category/Product-Name.htm with a 301 code.

There's 3 reasons for this:


Maintains parity with links.
Google will eventually rewrite with the new URL but while it doesn't, the old one will still work.
It should be standard practice when you're moving content to new URLs. This will be good practice!
