We understand software migrations are a delicate process and are here to help. Start by taking a look at the FAQ notes below for Junos software upgrades. There are links to resources that can help you understand our software support timelines, recommended latest supported versions of Junos for your device, and much more.
Another key resource to explore is the Junos Software Versions Knowledge Base article; it provides guidance on releases to consider and evaluate by Platform.
If you have any questions, please reply to the discussion and we will be happy to answer.
Juniper strives to provide the latest cutting-edge technology and features, although we've noticed many customers are still using end of support (EOS) software on their devices. Supporting customers on EOS software spreads our resources thin, and customers aren't taking advantage of our new features and resiliency.
**Please note upgrade guidance might not be complete for all implementations or configurations. Before proceeding with an update please ensure you have tested in a lab environment and/or have a backup copy of the original configuration. If urgent assistance is needed, please open a JTAC ticket (available through June 30, 2023, for Junos 10.x, 11.x, 13.x upgrades).**

Hello all, good day ! I tried to upgrade a 2-member Virtual Chassis, comprised of EX4300-32F, FROM JUNOS: 14.1X53-D46.7TO JUNOS: 21.4R3-S3I'm trying to find a way to upgrade them without any disruption (don't know if it's possible), tried to use NSSU with no success.Guidelines I took from JTAC was I should upgrade the VC at once, rebooting the two switches and NSSU is not fully granted. Would you have some advise/best practice on how to do it wihtout rebooting the entire VC ?I really appreciate it.Kindly regards,
Hello again Marco,
For best practices pertaining to EX VC upgrades, this is a comprehensive document that you can follow:
Upgrading to a release that is more than three major releases away, is not supported with NSSU. In your combination, the switch needs to be upgraded to multiple intermediate releases before it can be finally upgraded to 21.4. However, there are two things to note here:
1. It needs to be thoroughly tested in the lab with production configuration before it can be attempted in a live environment.
2. There is a supported release matrix for EX or QFX VC upgrades. What that basically means is, there are certain from and to combinations of use cases, only where an NSSU virtual-chassis upgrade will be supported and can be performed without disruptions. You will need to get in touch with the JTAC engineers to see if your combination is supported or not.
As far as the Pre-requisites and CLI procedure are concerned, you may consult this document:
Hope this helps!
