Please note the very important info below:
Support for upgrades and downgrades that span more than three Junos OS releases
at a time is not provided, except for releases that are designated as Extended
End-of-Life (EEOL) releases. EEOL releases provide direct upgrade and downgrade
paths—you can upgrade directly from one EEOL release to the next EEOL release
even though EEOL releases generally occur in increments beyond three releases.
You can upgrade or downgrade to the EEOL release that occurs directly before or
after the currently installed EEOL release, or to two EEOL releases before or
after. For example, Junos OS Releases 14.1, 14.2, 15.1 and 16.1 are EEOL
releases. You can upgrade from Junos OS Release 14.1 to Release 15.1 or even
from Junos OS Release 14.1 to Release 16.1. However, you cannot upgrade
directly from a non-EEOL release that is more than three releases ahead or
behind.
To upgrade or downgrade from a non-EEOL release to a release more than three
releases before or after, first upgrade to the next EEOL release and then
upgrade or downgrade from that EEOL release to your target release.
For more information about EEOL releases and to review a list of EEOL releases,
see https://www.juniper.net/support/eol/junos.html.
Sounds like you’ll need to go to 15.1, then 16.1, then 16.2.

Subject: Re: [j-nsp] upgrading an antique 240
Good point! TSB16735 says last version of Junos to support SCB-MX960 is 16.2
Junos 17.3R3-S10
Junos 18.4R2-S5
Junos 19.3R3-S2
Junos 19.4R3-S3
so which steps to get from 14 to 16.2? 15.x 16.2?
