It is true that the official path will tell you that you should follow from 15 to 16 then 17 then 18 but I did around 30+ upgrades from 16 to 18 without any problems. >From 10 to 15 I guess you should go to 14 first but from 16 you can safely move to 18 without any issues. The ones I am talking about are non-issue upgrades.

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. -- regards Tobias _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
