I have exchange2013 cu6 running on server 2012r2 with the latest patches on all. Internal and external DNS (split DNS) and all features are finally working correctly. It's not in production yet as testing was just completed. I just wanted to confirm that installing CU7 will leave all the settings in place.
Or will I have to redo some settings?
The CU6 will of course be backed up first.
