The following ``update-server`` command updates the maintenance start time of a Chef Automate server
named ``automate-06`` in your default region. The ``--preferred-maintenance-window`` parameter is
added to change the start day and time of server maintenance to Mondays at 9:15 a.m. UTC.::

  aws opsworks-cm update-server --server-name "automate-06" --preferred-maintenance-window "Mon:09:15"
