I am looking to upgrade my Exchange 2013 (has no CUs on it currently) to CU13. I see that there are potentially a few preparation commands that need to be ran on my AD/DC. Are these necessary to be ran or if I run the setup.exe for the CU13 release will that be included automatically? I remember when I did a CU update for 2007 it was included and didn't have to be ran separately in the Command prompt.
Also, any known issue that I may come across that you guys have encountered?
