Understood. Will do that.

At the same time, do you know if there is a way of installing

JunOS, like a fresh install, without upgrading?

I am asking that because that would allow us to upgrade 

our software directly to a newer version.

I saw those manual pages below where they use the word

"install" and not "upgrade" but did not understand

if that means a fresh install or something else:

Again thank you for your answer!

Hello Fred,

Regarding fresh installing Junos without an upgrade, you can perform a USB upgrade to directly move to a newer version. Please note that the USB upgrade will wipe out the existing configuration. 

The keyword "install" used in https://www.juniper.net/documentation/us/en/software/junos/junos-install-upgrade/topics/topic-map/install-software-on-srx.html   does not imply a fresh install (which I assume you mean upgrade software directly to a newer version). 

A Juniper Networks device is delivered with Junos OS preinstalled. When it is powered on, it starts (boots) using the installed software. As new features and software fixes become available, you must upgrade your software to use them.

Upgrading the version of the operating system on a device is done by copying a software installation package to the device or other system on your local network and then using the CLI to install the new software on the device. You then reboot the device, which boots from the newly installed software.

To summarise, you can directly move to a newer release by performing a USB upgrade or if you can share the current version the devices are on, the target version that you plan to upgrade to and platform details I can help you with the shortest upgrade path possible which is tested in our labs.

Hello Fred,

The shortest upgrade path from 15.1X49 to 22.4R2 for SRX which is tested in Juniper lab is:

15.1X49-D170.4 > 19.4R3 > 22.3R1.9 > 22.4R2

Note:

The tests were performed with baseline configuration and no line cards. 

We suggest using the no-validate option while performing upgrades. Please ensure to install the OS packages wherever applicable.

It is recommended to test the upgrade in the lab with the complete configuration before performing in production. Ensure all the hardware components are compatible with the recommended target release.

This is good to know.  I was told that Junos should only be upgraded in 1 main version at a time. like this... (actually I previously understood that Junos could/should only skip 2 sub-releases at a time, but since then, I've been told that you can go from one main version to the next main version)

19.4 - if you are here
20.1 - you can skip
20.2 - you can skip
20.3 - you can skip
20.4 - upgrade
21.1 - you can skip
21.2 - you can skip
21.3 - you can skip
21.4 - upgrade

...like that.   But you mentioned you could go from 15.1X49-D170.4 > 19.4R3 > 22.3R1.9 > 22.4R2.... so that's a lot faster to get where you want to go.

Hello Fred,

You can raise a TAC case requesting the release. They will provide a private link to you to download 19.4R3-S3. 

About USB upgrade: If you are doing USB upgrade, you need not follow the upgrade path. However, upgrade window in such cases will be longer since it will wipe out the configuration.

Although mine aren't SRX, but, NG-RE's in MX, I recently did the USB upgrade from 17.4R2-S10 to 22.2R3-S2.8 and it was fine.  I saved the config before, and put it back in after.  MW is needed, as there is lots of downtime.  Ask JTAC if SRX is ok to upgrade like that too.
