When selecting the Advanced Options button in the Hot Standby dialog you get the
opportunity to allow different firmware versions on the Primary and Standby
controller while running in full Hot Standby mode.
This lets you upgrade the controllers step by step to a new firmware version without
having to shutdown the system. Since this is only necessary in rare situations, it is
recommended that you disable this mode by configuration and to enable it by the
reference data editor when needed. By default, the controllers must have the same
versions of firmware. This means the Standby controller would not go online while
having a newer or older firmware version than the one on the Primary controller.
Note: This option is available only in Hot Standby systems already running with
Concept 2.5.
