Downgrading from FastIron 09.0.10a or Later to 08.0.70 or Earlier
When downgrading from FastIron 09.0.10a or
later to 08.0.70 or earlier on an ICX 7650, licensed features will be lost unless
there is a
pre-installed XML license on the device. Licensed features that have an XML license
will be
retained during the downgrade.
Downgrading from FastIron 09.0.10a or later to a release between 08.0.80 and 08.0.95 will not impact licensed features.
Because of the many software design and CLI changes implemented in FastIron 09.0.10a, downgrading to a previous release is complex and may produce unexpected results.
Note: Downgrading software is not recommended.
