-- | Indicates that minor version upgrades will be applied automatically to

--
-- Constraints: This parameter must be set to true when specifying a value

-- the replication instance\'s current version.

-- | The weekly time range (in UTC) during which system maintenance can
-- occur, which might result in an outage. Changing this parameter does not
-- result in an outage, except in the following situation, and the change
-- is asynchronously applied as soon as possible. If moving this window to
-- the current time, there must be at least 30 minutes between the current
-- time and end of the window to ensure pending changes are applied.
--
-- Default: Uses existing setting
--
-- Format: ddd:hh24:mi-ddd:hh24:mi
--
-- Valid Days: Mon | Tue | Wed | Thu | Fri | Sat | Sun

-- Constraints: Must be at least 30 minutes
