Delete Duplicate Addresses and Services

Hi,

I am migrating ScreenOS configuration to SRX. But I got task to remove all duplicate Addresses & Servcies and also if any services created has matching predefine Service replace it in Service and policy e.g. predefine Servcie is HTTP and someone created custome servcie like tcp-80 or udp-80. I need to replace both custom services to HTTP. 

My question is that is there any tool available to do these task or I have to do it manually.
