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.
Warning
It is highly recommended to ensure you have a database backup in place before booting stroom with a new version. This is to mitigate against any problems with the migration. It is also recommended to test the migration against a copy of your database to ensure that there are no problems when you do it for real.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 migrage command to just migrate the database and not fully boot Stroom.
See migrage command for more details.
Migration Scripts
There are no database migrations in v7.7.
