Downgrading JUNOSe Software

Downgrading JUNOSe software requires factory defaults installed on the router, and can cause NVS and configuration script incompatibilities.

CAUTION: We do not recommend that you attempt to downgrade JUNOSe software without the assistance of a Juniper Technical Assistance Center representative. Contact the Juniper Technical Assistance Center to obtain help.
