Expired passport and visitor visa

[Mehul123]

Our family member who would like to visit USA on visitor visa has the following situation:
(i) Indian Passport is expired and expired passport is having a valid visitor's visa
(ii) He has got the new valid (renewed) Indian passport.

If he has to visit USA, does he need to get valid visa transferred to new valid passport? OR It is ok to visit USA as long as he carries both the passports (New Indian valid passport without visa AND old (expired) passport with valid visitor's visa) while visiting USA?

I will appreciate your answer.
