Hello,
I would like to install Exchange 2013 into my existing Exchange 2010 / Office 365 environment but I do not want to introduce it into "production" until I had a play with it and configured it the way I want to before I allow it to accept connections and proxy to EXCH2010 for clients connecting up.
My understanding is until I update the AD SCP to point to new server and my internal/external DNS, the new EXCH2013 installation will not be detected by clients.
I also need to make sure the EXCH2013 will not modify any settings on my existing EXCH2010 (such as virtual directory URLs, etc..)
Is this correct?
