This should answer your question. Look for "From Economy to Premium Plus". Both business and economy upgrade awards are listed, flying Mainland US to South Asia (?).
Depending on your fare class upgrading from and the availability of upgrade space (big question), shouldn't be more than 30k miles, no copay. However, you made the right call IMO to buy up.
