Louis, for reason (I assume some issue) is TAC saying that a host-upgrade solves something?  I also assume from Junos SW point of view, you plan to stay with 14.1X53-D43, yes?

BTW, in the future solution to this is to perform Host Upgrade at same time as Junos Upgrade, using the force-host option - https://www.juniper.net/documentation/en_US/junos/topics/task/installation/qfx-series-software-upgrading-cli.html

Best of luck, Rich

    This is now my philosophy as well. Just working on cleaning up the mess w/as little impact as I can.

    Yes, and clarification from JTAC is that they need to be the same major version, which doesn't sound unreasonable.
