Rollback from OS10 release 10.5.2.0 or later to 10.5.0.9 or earlier

To move to an earlier release, use the rollback script that is bundled with your OS10 software image. 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. To view the version of the standby image, Use the show boot detail command.

NOTE:The rollback script reboots the OS10 switch immediately. The system removes any configuration changes that you have made in the new release when you run the rollback script.

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.
