Downgrading a Stack to a Release Prior to FastIron 09.0.10a
The major format change for stacking in
the FastIron 09.0.10a is the inclusion of the ethernet keyword before
port IDs (for example, stack-port ethernet 1/2/1) in the stack-port, stack-trunk, multi-stack-port, and
multi-stack-trunk
commands.
To downgrade to a release prior to FastIron 09.0.00 in the 08.0.9x format, copy the old startup-config file you saved previously back to the ICX device. The following example downgrades an ICX 7550 device by copying the file named saved_startup_08095 from the server at the specified IP address and saving it as startup-config.

If you have backed up the configuration and you use the correct saved startup-config file, the stack will remain intact. However, if the stack breaks for any reason, such as a power failure, use the recovery procedure (Recovering a Broken Stack After a Downgrade from FastIron 09.0.10a or Later) to re-establish the stack and stacking connections.
