Guess I'm living in the dark ages, but for the first time while pre-reading before installing an Exchange 2013 CU, I noticed that it is recommended to put the server in maintenance mode prior to proceeding with the install. I read somewhere else that the set up automatically does this for you, but in more than one spot it is shown to manually do this - not sure which way to go. We have a very small set up with a single domain and a single Exchange server (so no doubt it will be unavailable to users during the upgrade).
My actual question for the forum is that every article I see saying to put it in maintenance mode, also indicates to redirect messages to another server - which we obviously can't do since we only have one server. ("Redirect-Message -Server <ServerName> -Target <MailboxServerFQDN>"). My question is probably kind of simplistic, but just want to make sure I don't overlook anything - Am I just to skip this step, ignoring it completely? Or since we are a single server shop (all roles on one server), is going to maintenance mode even really needed at all?
Thanks in advance for any input.
