As others said, direct upgrade is somewhat unsupported and quite bold. We're currently upgrading mx480s from 13.3R5 to 17.2R2 with an intermediate step on 15.1F5. As those are LNSes we have to activate tomcat (`services subscriber-management`) while in 15.1, then continue the upgrade. For downgrades besides deleting the subscriber-management configuration we disable GRES and commit sync, and it goes smoothly.
