Upgrade Procedures
This section helps you choose the procedure to follow for upgrading your Solace PubSub+ Appliances to SolOS-TR 10.25 or earlier supported versions.
You may upgrade your event broker when all of these conditions are met:
-
The target version is numerically higher than your current version
-
The target version was released after your current version
-
The target version was released while your current version was still within its active support period
For example, upgrading from version 10.10.1.189 (June 2025) to 10.11.0.132 (January 2025) is not supported. Although the upgrade is to a higher numbered version, and was released while the source version was within its active support period, the target version was released before the source version.
To check the release date for specific versions, see the release notes for that version at products.solace.com.
To check the support period for specific versions, see Support Dates for Release Versions.
