Upgrade Notes

Required actions and information relating to upgrading to Stroom version 7.7.

Java Version

Stroom v7.7 requires Java 21. This is the same java version as Stroom v7.6. Ensure the Stroom and Stroom-Proxy hosts are running the latest patch release of Java v21.

Configuration File Changes

Stroom’s config.yml

No changes have been made configuration file.

Stroom-Proxy’s config.yml

No changes have been made configuration file.

Database Migrations

When Stroom boots for the first time with a new version it will run any required database migrations to bring the database schema up to the correct version.

On boot, Stroom will ensure that the migrations are only run by a single node in the cluster. This will be the node that reaches that point in the boot process first. All other nodes will wait until that is complete before proceeding with the boot process.

It is recommended however to use a single node to execute the migration. To avoid Stroom starting up and beginning processing you can use the migrate command to just migrate the database and not fully boot Stroom. See migrate command for more details.

Migration Scripts

There are no database migrations in v7.7.
