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 router. To downgrade to an earlier version of software, follow the procedure for upgrading, using the JUNOS Enhanced Services software image labeled with the appropriate release.

Note: This procedure applies only to downgrading one release of the JUNOS Enhanced Services software to another. To downgrade the JUNOS Enhanced Services software to the JUNOS software, see the JUNOS 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 router.

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

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