I am getting ready to install Lync 2013 and have a couple questions.
Removing and deactivating LCS 2005
I already have LCS 2005 and I plan to remove this before install Lync. I have a front-end server and an Access Proxy setup.
I am following the guide here to do this. Do I need to deactivate the LCS proxy and uninstall it first or the front-end server?
Question Regarding Remote Administration Tools
My Lync 2013 server will be running on Server 2012. It tells me that I need to install remote administration tools on the front-end server. My domain and forest level is 2003. This won't affect anything will it?
I don't have CA installed on my domain controller. I was just planning on using digicert for my external and internal certificates. Is this possible?
