How does Tier 2 Certificate Server works
I have a question regarding standalone root CA. I understand when we create the root CA, we will have to create a private key that only the root CA has. And it is used to encrypt or decrypt messages with other clients with the public key.
My question is if we have subordinate CA in the domain. Then we will put the root CA offline so no one can touch the private key. But if we put root CA offline, then no one else has that private key. So Do the root CA pass the private key to the subordinate CA?
Thank you so much

No; the root CA signs the subordinate (and marks it as allowed to sign other certs). You should never transfer private keys.
