Downgrading from a Higher Release
Procedure
Step 1 Locate the image files you will use for the downgrade by entering the dir bootflash: command.
If the image files are not stored on the bootflash memory, download the files from Cisco.com:
a) Log in to Cisco.com to access the Software Download Center. To log in to Cisco.com, go to the URL
http://www.cisco.com/
Note
b) Access the Software Download Center using this URL:
http://www.cisco.com/kobayashi/sw-center/index.shtml
c) Navigate to the software downloads for Cisco Nexus 5000 Series switches.
You see links to the download images for the switch.
d) Read the release notes for the related image file then select and download the kickstart and system software
files to a local server
e) Ensure that the required space is available in the bootflash: directory for the image file(s) to be copied.
Caution
f) Copy the kickstart and system images to the switch bootflash using a transfer protocol. You can use ftp,
tftp, scp, or sftp.
Step 2
Install the new images.
Example:
switch# install all kickstart bootflash:n5000-uk9-kickstart.4.0.1a.N1.0.62.bin system
bootflash:n5000-uk9.4.0.1a.N1.0.62.bin
The install all command performs the following actions:
• Performs compatibility checks (equivalent to the show incompatibility command) for the images that
you have specified. If there are compatibility issues, an error message is displayed and the installation
does not proceed.
• Displays the compatibility check results and displays whether the installation is disruptive.
• Provides a prompt to allow you to continue or abort the installation.
Note
• Updates the boot variables to reference the specified images and saves the configuration to the startup
configuration file.
Step 3 After the switch completes the installation, log in and verify that the switch is running the required software
version.
Example:
switch# show version

Unregistered Cisco.com users cannot access the links provided in this document.
We recommend that you keep the kickstart and system image files for at least one previous
software release to use if the new image files do not load successfully.
A disruptive installation causes traffic disruption while the switch reboots.
