Changes to Upgrade for Stacking from FastIron 08.0.90
The stacking port format is different beginning with FastIron 08.0.90. The change in format creates upgrade issues.
Upgrading a Stack to FastIron 08.0.90 or Later from Earlier Releases
Upgrades from earlier releases to FastIron 08.0.90
or later are seamless. FastIron 08.0.90 and later recognize the old format and
parse
the startup-config flash to convert the configuration to the new format. After
upgrade, if you enter the
write memory command to save the configuration, the new format is
stored to the startup-config flash.
In the following example, an ICX 7550 stack is
upgraded to FastIron 08.0.90 from the FastIron 08.0.80 startup-config flash. The
user has not yet used the write memory command. Output for the show configuration
command shows that the FastIron 08.0.80 startup-config flash remains in the old
format. The command output for the show running-config
command displays the runtime configuration in the new
format.
