I need to move my accessory products to alternative products.  I've been trying to do this inside of Odoo with no luck.  Eventually I came up with these SQL commands which seem to do the trick, but I was wondering if this might be harmful to run on production or if anyone knew a cleaner way?

TRUNCATE product_alternative_rel;

INSERT INTO product_alternative_rel SELECT DISTINCT src_id,product_tmpl_id AS dest_id FROM product_accessory_rel, product_product WHERE dest_id = product_product.id;

TRUNCATE product_accessory_rel;

Any advice appreciated.
