Downgrading from a Higher Release

The procedure to downgrade the switch is identical to a switch upgrade, except that the image files to be

loaded are for an earlier release than the image currently running on the switch.

Prior to downgrading to a specific release, check the release notes for the current release installed on the

switch, to ensure that your hardware is compatible with the specific release. There are special caveats you

must be aware of before you downgrade the switch software to a 4.0(0)-based release. See the Cisco Nexus

5000 Series and Cisco Nexus 2000 Series Release Notes for details.

Note

To downgrade the software on the switch, follow these steps:
