EFM Cluster Database Setup

Before you first run or launch the cluster, you must install and configure MySQL or PostgreSQL.

For more information, see Installaing Databases.

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

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