     With the replication stream running, you can monitor the job via the DB Console, SQL shell, or Prometheus. You can also verify data is correct on the standby cluster at a specific point in time.

 ## Set up PCR from an existing cluster
 
 You can set up PCR replication from an existing CockroachDB cluster that does not have [cluster virtualization]({% link {{ page.version.version }}/cluster-virtualization-overview.md %}) enabled. However, the standby cluster must have cluster virtualization enabled. In the [PCR setup]({% link {{ page.version.version }}/physical-cluster-replication-technical-overview.md %}), the existing cluster is the primary cluster.
