See Installing licenses for Broadcom-supported BES-53248 cluster switches for details of the firmware versions supported for available licenses.

Warning: If you need to downgrade the switch software from version 3.4.4.6, the licenses are removed. This is expected behavior.

You must install an appropriate older license before reverting to an older version of the software.
