11. If the saved configuration from Release 10.5.0.0 (or the earlier release to which you are downgrading to) is available, apply

the saved configuration and license files, and reload the switch.

OS10# copy ftp://userid:passwd@hostip/filepath/10.5.0.0-startup.xml config://

startup.xml

OS10# license install scp://user:passwd@hostip/0A900Q2-NOSEnterprise-License.xml

OS10# reload

NOTE: While reloading, if the CLI prompts to save, select no for the save option. Selecting yes overrides the

configuration that was copied earlier.

12.

If the saved configuration file from Release 10.5.0.0 (or the earlier release) that you are downgrading to is not available,

apply the backup text configuration (.txt) taken in Step 3. Ensure that the backup configuration text file does not have any

unsupported commands (commands that are introduced in later releases). If unsupported commands are present in the text

file, the system errors out. You might have to reload the switch, if any of the configurations require a reload.

OS10# copy ftp://userid:passwd@hostip/filepath/backup-running-configuration.txt

running-configuration

OS10# write memory

OS10# reload

Roll back from 10.5.2.0 or later release to 10.5.0.x or earlier release

Use the rollback script that is bundled with your OS10 software image to move to an earlier release. Using the rollback script

retains the earlier configuration and license information. You can use the rollback option only when the previous image is

available in the system as the standby image. Use the show boot detail command to view the version of the standby

image.

NOTE: The rollback script reboots the OS10 switch immediately.

To roll back, from the Linux shell prompt, enter:

OS10# system bash

bash (OS10) $ sudo os10-rollback-to-old-image

NOTE:

After rollback is complete, the system comes up with the previous release. However, the standby image becomes

nonbootable. To boot using the standby image, you have to install the image again using the image install command.

Downgrade to Release 10.5.1.0 or later releases

In this example, the OS10 switch runs the 10.5.2.0 software and the following procedure downgrades the system to Release

10.5.1.0.

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 the Rollback from 10.5.2.0 or later release to 10.5.1.0 or later 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 to 10.5.1.x.
