Edge Flow Manager cluster database setup

Before you first run or launch the Edge Flow Manager cluster, you must learn how to install and configure MySQL, MariaDB, or PostgreSQL.

For more information, see Installaing Databases.

You can use an existing external database of a single and standalone Edge Flow Manager instance for the cluster deployment. None of the existing data will be lost.

However, you cannot use an H2 database of a standalone Edge Flow Manager instance and you must start over with an external database. When moving from H2 to MySQL, MariaDB, or PostgreSQL, prior to stopping the standalone instance, export the existing flows from the Edge Flow Manager Flow Designer and import into the cluster to avoid data loss. For more information on exporting and importing flows, see the REST API Reference.
