Best way of Cloning Issue Which force user to fill mandatory and replace older value

[Vikrant Yadav]

Hi Experts,

I am very confused, User is asking to clear the mandatory field at the time of cloning the issues. 

For this i can create an automation which only copy those value which user want to retain, but mandatory field what I am thinking to set value N/A. But this will force user to change the mandatory field value. 

Kindly suggest what would be best approach to clear mandatory field at the time of cloning and asking to fill those mandatory field after cloning.
