    Also whether you can mechanically reuse a model to generate predictions is separate from whether the model is going to make sensible predictions for the new use case.  In the case of demand forecasting, you would need to ask yourself whether the relationships captured for the product on which the model was originally built are likely to be consistent with the relationships you would expect for the new product.  If they are similar products then this may be plausible.  But if the products are different, then this is likely not a good assumption and you would be better off training a new model on the other product.
