Dell SmartFabric OS10 User Guide Release 10.5.3

Rollback from 10.5.2.0 or later release to 10.5.1.0 or later release

The following rollback procedure 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.

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 the earlier configuration used in that release or license data.

1. Use the show boot detail command to view the standby image.

   OS10# show boot detail
