Purchasing a test certificate then implementing it to production
We currently have a cert with the domain www.domain.com
We need to purchase a test certificate in order to implement a new login portal to production environment.
My scenario is that we have a current domain www.domain.com, and we want to implement a new login portal.
We'd like to test the certificate so I'm wondering how to go about purchasing a test certificate, installing the certificate in the test environment and then replacing our current production certificate.
Is this possible? What are the steps needed to get this accomplished?
