Downgrading the Software with the J-Web Interface

You can downgrade the software using the J-Web interface. When you downgrade the software to a previous version, the software version that is saved in junos.old is the version of the JUNOS software that your router is downgraded to. For your changes to take effect, you must reboot the router.

1. Go to Manage>Software>Downgrade. The previous version (if any) is displayed on this page.

   After you perform this operation, you cannot undo it.

2. Select Downgrade to downgrade to the previous version of the software or Cancel to cancel the downgrade process.
3. When the downgrade process is complete, for the new software to take effect, click Manage>Reboot to reboot the router.
