Hi All,  
I am trying to find a way to perform replication from the Primary Xtradb 8 Cluster to DR(disaster recovery) Xtradb 8 Cluster.  
The Primary Xtradb 8 Cluster will write data from application output and on the DR site, I have a second Xtradb 8 Cluster which needs to replicate data coming from the Primary Xtradb 8 Cluster.

Can someone please suggest how to achieve it?

Thanks  
Adi

Hello @adi,  
You need to configure async replication between a node in primary PXC and 1 node in DR PXC. You can use [Async Failover](https://dev.mysql.com/doc/refman/8.0/en/replication-asynchronous-connection-failover-source.html) on DR node to switch sources if the source on the primary PXC goes down.

Hi @adi , welcome to the Percona forums!  
You may want to review this blog post that discusses precisely how to replicate between PXC clusters:
