We are in the process of deploying exchange 2013 to phase out an old 2007. I've spent quite a bit of time discovering and preparing the install. However, I have one questions that I can't seem to find a correct answer. I am using a trusted CA on my existing 2007. At what point do I need to export and import this CA onto the new 2013 without causing any issues?
Thanks for any help.
