Junos OS

Dear team:

First some background :o)
My customer wants to upgrade the JUNOS of one MX104 router from its current version 13.3r3 to version 21.2. A giant leap!
The current state of the router is "factory default". Fully operational, but doing nothing. No traffic passing through it.

I have been recommended many times to execute the upgrade as a set of accumulative software upgrades up to the destination version . But I wonder if, in this case, this boring process of intermediate JUNOS upgrades can be avoided. 

¿ Can I just put the corresponding "install package" of version 21.2 on the /var/tmp of this router and execute the classical "request system software add /var/tmp/<name of the package> no-copy no-validate" command? I believe so. 

Please remember this router is doing nothing useful. In fact, it actually has the factory default configuration. So I have total freedom to execute at will, but I want to execute as fast as possible :o) 

Your kind hints will be greatly appreciated.
Thanks!

The standard upgrade will not be supported and likely cause issues.

Create a bootable usb with snapshot
Boot from this usb
run the install with media format from the usb as a clean install

Hello Steve!

Yes. I finally followed the advice as mentioned by you and other colleagues in this forum, and executed from a bootable USB. Everything ran smoothly and the process took no longer than 10 minutes.

Thanks!
Rogelio
