Upgrade Considerations


Before upgrading please review the Upgrade Considerations and the Rolling Back Software pages. Several modifications have been made to the process for verifying configurations, which will impact existing configurations.

  • I95-43243/IN-460 Upgrade and Rollback: Upgrading or rolling back a system (conductor peer or router) with the interactive installer install128t, that is managed by a conductor may result in the system becoming unresponsive. It is highly recommended that upgrades be performed through the conductor UI. Manual upgrades and rollbacks may not be resilient to failures. See Rolling Back Software for more information on these operations.

  • I95-42452 Conductor Upgrade Time: Upgrades to version 5.4 and above can take up to 40 minutes due to the number of rpms being upgraded. Please plan accordingly.

  • I95-42624 Upgrade Installer: Before upgrading to, or installing version 5.4 and above, update the Installer to at least version 3.1.0. Failing to upgrade the installer may result in a rollback failure, should a rollback be necessary at any time.

  • Plugin Upgrades: If you are running with plugins, updates are required for some plugins before upgrading the conductor to SSR version 5.4.0 or higher. Please review the Plugin Configuration Generation Changes for additional information.

The Juniper SSR team does not publicly disclose known or resolved CVEs in our public documentation but instead utilizes our internal bug tracking IDs. Customers can obtain the actual CVE numbers by contacting Juniper Support.

Release 5.5.8-7

Release Date: February 1, 2023

New Features

  • I95-47947 Increase max CoreDump size to 4GB: The maximum size of coredumps now defaults to 4G. This value can be configured in environment config by modifying the maxCoredumpSize field of the new crashReporting object. Any manual modifications to coredump.conf will be overwritten whenever the service is started.

Upgrading to this release version will cause coredump.conf to be re-written with 4G limits for coredumps even if coredump.conf had been updated manually for a higher value!

Resolved Issues:

  • The following CVE's have been addressed: I95-48464, I95-48644, I95-48648, I95-48650, I95-48653, I95-48907, I95-49039.

  • I95-45348: Update salt master and minion to 3002.8: When upgrading an HA pair to version 5.5.1, please be aware of the following: While updating the conductors in an HA pair, the upgraded conductor node asset state will remain DISCONNECTED if the active automatedProvisioner is not running a corrected version (see table below). When performing an HA conductor upgrade the node running the oldest software assumes leadership. However, the older version will not be able to talk to the new software on the upgraded conductor.

The active automatedProvisioner can be determined by running the command show system processes. Once the upgrade begins on the old node, the newly upgraded conductor takes over.
