Orion requires Java 11+; earlier versions are not supported.

For production systems, we recommend running Besu and Orion in separate instances. If running Besu and Orion in the same instance, restrict the amount of memory used by each JVM to ensure each has enough memory.

Version compatibility

The latest minor version of Orion is compatible with the latest minor version of Hyperledger Besu. That is, upgrading Besu from 1.4.x to 1.5 requires upgrading Orion from 1.5.x to 1.6. Upgrading from Besu 1.4.x to Besu 1.4.y does not require an Orion upgrade.
