"To downgrade from Release 13.3 to another supported release, follow the procedure for upgrading, but replace the 13.3 jinstall package with one that corresponds to the appropriate release."


"Note: After you install a Junos OS Release 13.3 jinstall package, you cannot issue the request system software rollback command to return to the previously installed software. Instead you must issue the request system software add validate command and specify the jinstallpackage that corresponds to the previously installed software."
