Downgrade to Release 10.5.0.0 or earlier releases
NOTE:
● If the version that you are downgrading to is present in the system as the standby image, you can rollback to that
release without losing any configuration or license data. Use the show boot detail command to view the standby
image version. See Rollback from 10.5.1.0 or later release to 10.5.0.0 or earlier release for more information.
● If the image that you are downgrading to is newly installed using the image install command, backup of the original
configuration data will not be available. The system boots with the default configuration. If you have a copy of the
backup configuration file (.xml) obtained from the earlier release that you are downgrading to, you can apply the saved
configuration and license files as described in Step 11 of the following procedure.
Prerequisites
Obtain a backup of the configuration data. Ensure that you have a copy of the license files. Reapply the configuration data and
licenses files after you reload the 10.5.0.0 or earlier image.
1. Upgrade the ONIE to the latest version on the switch that is being downgraded.
2. Upgrade the Firmware to the latest version on the switch that is being downgraded.
3. Back up the current running configuration to an external storage.
OS10# copy running-configuration ftp://userid:passwd@hostip/filepath/10.5.2.0-running-
configuration.txt
4. Back up the startup configuration (startup.xml) to an external storage.
OS10# write memory
OS10# copy config://startup.xml ftp://userid:passwd@hostip/filepath/10.5.2.0-
startup.xml
5. Download the OS10 binary image for Release 10.5.0.0 from a local server using the image download server-
filepath/filename command in EXEC mode; for example:
OS10# image download sftp://admin:passwd@10.1.1.1/home/admin/images/OS10EE.bin
6. (Optional) View the current software download status in EXEC mode.
OS10# show image status
7. Install the OS10 standby image using the image install file-url command in EXEC mode, where filename is the
name of the image file that was downloaded in Step 5 with the image download command; for example:
OS10# image install image://OS10EE.bin
8. (Optional) View the status of the software installation in EXEC mode.
OS10# show image status
