# Roll back the SMC Appliance to the previous version on the command line

To revert changes made by a patch that has been installed, you can roll back the SMC Appliance to the previous configuration if needed.

##

Note: When you roll back the SMC Appliance, configuration changes made after the current version was installed are lost. We recommend rolling back as a recovery option only for a short time after an upgrade.

## Steps

1. From the command line, log on to the SMC Appliance.
2. Enter the following command:

       sudo smca-system toggle

3. Restart the SMC Appliance.

## Result

When the SMC Appliance restarts, the previous SMC Appliance configuration is in use.
