Downgrading the Software with the CLI

You can revert to the previous version of software using the request system software rollback command in the CLI. For the changes to take effect, you must reboot the device. To downgrade to an earlier version of software, follow the procedure for upgrading, using the software image labeled with the appropriate release.

Note: This procedure applies only to downgrading one JUNOS software release to another or one JUNOS software with enhanced services release to another. To downgrade JUNOS software with enhanced services to the JUNOS software, see the JUNOS Software with Enhanced Services Migration Guide.

To downgrade software with the CLI:

1. Enter the request system software rollback command to return to the previous JUNOS software version:
   user@host> request system software rollback

   The previous software version is now ready to become active when you next reboot the device.

2. Reboot the device:
   user@host> request system reboot

The device is now running the previous version of the software. To downgrade to an earlier version of software, follow the procedure for upgrading, using the software image labeled with the appropriate release.
