Ceon URI Mapping v4.x

[DivaVocals]

Not auto-magically by itself. You will need to do some work.

You have a few options... As other people have mentioned... you can

1. Add your products and when adding them assign a unique URI via this module matching your old URI for the same product. (probably the best approach unless you plan to change your URIs as part of the move).
2. Use a RewriteRule to rewrite the old requests to match the new requests. This lets both the old URIs and new URIs co-exist at the same time. Zen Cart and this module work together to automatically provide search engines with a "canonical link" so they know the two URIs have the same content and the "canonical link" is your preferred URI to display and use in search results. (good approach if the old URIs followed a pattern and the pattern has similar components to the new URIs you plan to use - can be used instead of 301s in many cases).
3. Use a 301 redirect to point each individual old URI to the new URI (personally my last choice - an option if you must change the URI or the hostname as part of your move).

Option one will not occur a penalty for the URI change... as no URI change has occurred. Option two usually does not incur a penalty (read more about canonical links). Option three usually incurs a slight negative penalty due to the URI change.

and, unless I'm mistaken, Conor provided a HINT in his documentation how to achieve option one.. (a hint I posted about in my previous response)

but what do I know "living in my mom's basement sitting on this forum all day" and all..
