Hi,

I agree with suriyaehnop, we have to setup Exchange server with maintenance mode when install update with DAG.
We can use the Exchange 2013 Setup wizard to upgrade your current version of Exchange 2013, please refer to Installing update with DAG members section:

Besides, Microsoft recommend that install update on CAS server first, then MBX.
