Warning
SingleStore 9.0 gives you the opportunity to preview, evaluate, and provide feedback on new and upcoming features prior to their general availability. In the interim, SingleStore 8.9 is recommended for production workloads, which can later be upgraded to SingleStore 9.0.
Replication Compatibility Between Different Cluster Versions
In general, you can replicate data between two different versions of SingleStore if the SingleStore version on the source cluster is earlier than the version on the destination cluster.
See the Verify your cluster is ready for upgrade section of the upgrade guide for how to upgrade with replicated (DR) databases.
