How to automatically enroll and authenticate the trustpoint on cisco routes?

Hi Guys,

I would like to ask if there any way to automatically enroll and authenticate the trustpoint after updating the finger print?

We have hundreds of devices which we need to update the finger print since the old router(pki server) has been replaced due to hw defect. Now we need to update the finger print of the spoke routers.

So I would like to ask the ff.

1. Is there any way to automatically enroll and authenticate the trustpoint after updating the finger print? Currently we are manually updating the finger print and manually run the enrollment and authentication.
2. Is it possible to backup all certificate and the finger print of old defective device to the new device?

Thank you.
