Move categories and 301 redirect cpath

[Shop Suey]

Hello,
i moved some larger categories with sub-categories to one category above.
Should I 301 redirect the older cpath to the new cpath?

Here's a scheme of what I did:

1_2_3_4 -> 1_2_4
1_2_3_5 -> 1_2_5

Should I redirect via 301 or is it useless with cpath technology?

• 1_2_3_4 to 1_2_4
• 1_2_3 to 1_2_4? (_4 contains now the products of the older _3)
• 1_2_3_5 to 1_2_5

Last time I looked at how tools such as google webmaster looked at categories (cPath) I thought the category was identified as something like a non-designating parameter meaning that redirecting the category portion wasn't much help as it was the products_id that defines the product regardless of the category designation. Of course each base category (showing the list of product has changed).

That said, if you have a sitemap, then that should be updated to reflect the existence of the category(ies) though if new.

There may be others that suggest otherwise. I just don't see the need...
