User Guidelines
The configuration on the stack master switch controls the stack as if it is a
single switch. No configuration steps need to be taken on the member
switches to downgrade the firmware. Configuration migration during a
downgrade is not assured. The operator should ensure that the configuration
can be downgraded before allowing the downgrade to occur or otherwise take
steps to reconfigure the switches.
During a downgrade, meta-data regarding the stack configuration is not
migrated. For example, Ethernet ports configured as stacking ports will revert
to the default Ethernet configuration during a downgrade. When this occurs,
the stack will be split into individual switches, each of which must have the
relevant Ethernet ports individually configured as stacking before the stack
can be reconstituted.
