Our CA Is offline and apparently has been for quite some time. A little background, we have 5 domain controllers one is set as the PDC which is a 2008R2. We are in the process of upgrading all of them to new servers currently two are 2012R2 the other three will be upgraded over the next year.
Forgive my newness to this but what does a CA do and can I just go ahead and install the CA on one of the 2012R2 DC servers. What is involve in it or do I need to do? Converting it would be problem I no longer have a server with the name it was looking for. Do I need a CA?
