This upgrade is only supported for Junos OS 12.3X48-D80 and later releases, 15.1X49-D140 and later releases, and 17.4R1 and later releases. This is because the older Junos releases have an engine which is incompatible with the 1.380.0 major protobundle version. So the older Junos releases will remain on JDPI-Decoder version 1.340.0-73.005 and there will be no more updates for these releases.
