Evaluating a firmware upgrade

CAUTION

Because of potential compatibility issues, Brocade does not recommend restoring Network OS
v2.1.x after you upgraded to Network OS v3.0.0.

You can restore a previous firmware version after downloading and evaluating a newer (or older)
version by downloading the firmware to a single partition only. The previous version is preserved on
the secondary partition and you can restore it if necessary.

To enable firmware restoration on a compact switch, you perform the firmware download
operation with the option. This option prevents the firmware download from
copying the firmware to both partitions and committing the upgrade.
