Sorry for this comment from "google translation"
This plugin is not too bad actually, and especially it has the merit to exist.
I tried to adapt to the e-commerce solution Zencart (OsCommerce fork).
- It is very very slow for consistent data bases (several consecutive timeouts) -> more than 10 products migrated each script
- There is an error on the stock (I feel that the treatment combines quantities when a product is linked to multiple categories)
I'll try to see if there is no rapid improvement possible.
