Every Fredhopper instance in a SDL SmartTarget setup has one promotion named SmartTarget Meta Promotion (do not remove!)
. This promotions contains the medata SmartTarget uses to order the promotions and obviously -thoug tempting- this prmotion must not be removed.
Now I am cleaning up a Fredhopper instance to repurpose it, the instance is reindexed to clean all items, removing all promotions, etc. Can I safely remove this meta promotion as well?
