# 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](https://docs.singlestore.com/db/v9.1/user-and-cluster-administration/maintain-your-cluster/upgrade-or-uninstall-singlestore/upgrade-to-singlestore-9-1.md) section of the upgrade guide for how to upgrade with replicated (DR) databases.
