Migration from Luna Streaming 2.10
-
Upgrading to Luna Streaming 3.1 should only be done from Luna Streaming 2.10.
-
Upgrade is fully supported for all the components (connectors included).
-
Prometheus client version has been changed from 0.5.0 to 0.16.0. Metric type UNTYPED is renamed to UNKNOWN. The metrics have been renamed because OpenMetrics’s counter name needs a _total suffix.
-

Downgrade is not supported for Bookies and ZooKeeper. All other components such as Broker, Proxy and Functions Worker can be downgraded at any time.
-
Pulsar 3.1 uses RocksDB 7.x which writes in a format that is not compatible with RocksDB 6.x which is used by LunaStreaming 2.10 via Bookkeeper 4.14.
