Replacing cryptogen certificates with other certifcates issued by a CA in a production environment

Hello, 

I have deployed a fabric network in production environment with certificates generated with cryptogen tool. Now I need to replace those certificates with ones which are generated using Fabric-CA or any other CA. What would be the correct approach to achieve this. Is it possible to do a transaction configuration update where I replace the existing Certificates with the new ones and what will happen to the existing transactions (blocks) which are signed by the old certificates (cryptogen certs). Any help would be appreciated.
