11. If the saved configuration from Release 10.5.1.0 (or the later 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/10.5.1.0-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 10.5.1.0 (or the later 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
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 any configuration or license data.
1. Use the show boot detail command to view the standby image.
