Junos OS

To avoid disruption, we recommend checking whether your hardware has reached end of life (EOL), and identifying your upgrade path. If your hardware is running the last-supported software version (LSV), support will continue until your hardware's EOL date.

If you are on an a version of Junos 19.x or earlier,  please take a moment to complete this brief survey so we know how to best support organizations needing to upgrade.

Upgrading to newer Junos releases offers critical benefits, including:

• Enhanced security to defend against modern threats
• Improved scalability and performance for smoother operations
• Better cloud support and advanced routing capabilities
• Automation tools to simplify management and save time

Finding the appropriate upgrade pathway can be challenging, and we are here to help. Reply to this thread with your current Junos version and the version you are seeking to upgrade to.  The Juniper Services team is monitoring this post for your #UpgradeQuestions.

1. Why should I upgrade?
   1. A newer version of the OS includes new features, enhancements, and bug fixes. Learn more about the benefits of upgrading.
   2. We will no longer accept, or action, support cases for Junos releases 17.x starting on April 2, 2025, and releases 18.x and 19.x starting on Oct. 1, 2025. Don't delay! Start your upgrade process today.
   3. Exceptions: If your hardware is using the last-supported software version (LSV) for Junos, or if you have an existing ECCS contract, your support will continue until your hardware's EOL date, which you may locate here.
2. Are any hardware platforms excluded from this notification?
   1. Yes. As noted above, hardware running LSV versions of Junos maintain support until its EOL date, including:​
      1. The latest recommended release for the ACX6360-OX is Junos 18.4R1-S8 until September 1st 2027 .
      2. Junos 19.4R2-S2 is recommended for the ACX6360-OR until September 1st 2027.​

      6. If running FIPS mode MX10003 Junos 19.3R3 is recommended 
      7. If running FIPS mode EX4300-48MP Junos 19.4R3 is recommended.
      8. If running FIPS mode with SRX345 SRX380 or SRX1500 Junos 20.2R3 is recommended.
3. Why is there a last supported version of software for my device? 
   1. Juniper devices receive hardware updates as new software features and resiliency are developed. If your device is near or has passed its end-of-life date, the newer releases may not function due to differences in components or hardware architecture change requirements. 
4. Where can I find whether my device has a last supported software version (LSV)? 
   1. Refer to the Suggested Releases to Consider and Evaluate KB article. 
5. Where can I find end-of-support timelines for available Junos releases?
   1. Refer to the Junos OS Dates & Milestones  for timelines and some hardware-based exceptions. 
6. Where can I download newer software for my device? 
   1. Software can be downloaded from the Software Downloads Portal. You will need your product's (device) name to find the appropriate software. 
7. What are the upgrade steps?
   1. Verify your device is not past its end of life.
      1. Refer to End of Life Products & Milestones for device end-of-life status.
   2. Identify the target software to upgrade.
      1. The Suggested Releases to Consider and Evaluate article has information on suggested releases by device.
      2. Junos OS Dates & Milestones can help you understand support timelines.
   3. Determine software upgrade approach and upgrade path.
      1. If you have on-site personnel, using USB storage to complete the software upgrade can reduce complexity and save time. For standard Junos upgrades, refer to the Junos OS Software Installation and Upgrade Guide which contains detailed upgrade procedures. If you have specific questions on the upgrade path, feel free to post your questions on the community.
   4. Download software.
      1. Use the Software Downloads Portal.
      2. If you are unable to locate the desired software, reply to this post with your question or contact JTAC.
   5. Verify the configuration and take the configuration backup.
      1. Test the software upgrade.
8. How can Juniper help in planning the upgrade process to avoid any potential risks?
   1. Juniper provides detailed analysis services for software upgrade planning. Leverage the Software Upgrade Recommendation and Review or Network Optimization Consulting Services, to better assess the recommended software release for your network.
   2. Additionally, Juniper provides fully customized testing services to qualify Junos OS upgrade path testing and new target Junos OS release in Juniper Networks' internal physical testing lab environment known as Customer Certification Lab (CCL). Leverage Juniper Testing-as-a-Service (TaaS) offering to mitigate any potential risks to your network.
9. What if I encounter an issue when I am deploying the updated Junos software?
   1. To avoid issues in advance, please refer to the Software Upgrade Recommendation and Review or Network Optimization Consulting Services.
   2. Post questions in the Elevate community for peer and expert guidance.
   3. Raise a ticket with JTAC if you think you encountered a bug or gap in our upgrade procedures. Enter your target software release when the case is created to avoid case creation restrictions.
10. Who can I contact if I have questions and need assistance from Juniper?
    1. Post questions in the Elevate community for peer and expert guidance. Juniper technical personnel monitor communities and provide support.
    2. Contact your Juniper Account Manager or Juniper Partner Manager for personal guidance.
11. What if I clearly have a hardware problem that doesn't require tech support? I have an active service contract, so where can I get a field replaceable unit (RMA)
    1. Determining whether an issue is from software or hardware can be very difficult, especially with software that is end of support. If it is clearly a hardware issue you need to open a technical support case thru the Juniper Support Portal where you will be offered hardware support only when running one of these releases 17.x, 18.x, and 19.x.  You will need to enter defective part's serial number to initiate an RMA.
12. What should I do if my hardware is end of life too?
    1. You need to upgrade your hardware if it is EOL. Start that process today by contacting your Juniper Account Manager or reseller to discuss your options.
13. What should I do if I don't have a Juniper Account Manager?
    1. If you need assistance finding yours, complete this brief "Request a Call" form.
14. How is this EOS enforcement being communicated?
    1. Emails are being sent to companies that have opened a ticket for Junos 17.x, 18.x, and 19.x in 2023 or 2024.  This email is being sent from customer_success@customersuccess.juniper.net and is a valid notification.  Multiple notifications will be shared until the EOS enforcement dates. Communications include but are not limited to reminder emails and posts to the Elevate Community.
