To enable replications to the cloud, your environment must meet certain requirements in terms of additional configuration and specific versions of the VMware products that you use.
Disaster Recovery to Cloud has the same requirements to the environment as vSphere Replication. In addition, Disaster Recovery to Cloud requires that ports 10000 to 10010 of ESXi hosts are open for outgoing traffic . The required ports are open automatically when you install a VIB on each supported ESXi host in the environment where the vSphere Replication appliance is deployed. See How vSphere Replication Connects to Cloud.
Replications to the cloud require that you run certain versions of VMware products on the source site and on the target site. Your cloud provider ensures that the target environment is configured for replications to cloud. You must verify that you run a supported version of the following products on the source site.
|vSphere Replication appliance||6.x|
|ESXi host||5.0, 5.1.x, 5.5.x, and 6.0|
|vSphere Web Client||6.0|
