There are probably official upgrade pathes taking a dozen intermediate 
steps (three LTS releases at a time or something like that is officially 
supported, and starting from $some version in the 16/17 all releases are 
considered LTS). As The MX80 takes ages to do just one upgrade this 
would take days. Also it could be quite hard to actually get 
intermediate releases for the older steps (JTAC typically has them on 
request)

I would suggest to backup the config do a usb reinstall to the target 
release and reapply the config.
