Apple Pay on the web P12 key

We created the P12 key from the Merchant ID certificate using KeyChain Access when developing Apple Pay for web.

Now we are in the process of deploying Apple Pay to Prod, do we need to generate a new P12 key for Prod?

I am not sure about the process here, and need some assistance or understanding.

Do I need to create a new P12 for Production deployment or can I use the P12 created when developing?

Thanks
