The com.vmware.pso.vc.templatesync package provides a set of workflows that can sync VM templates between vCenter servers. The vRO appliance pulls the specified VM templates from a source vCenter, stores them locally, then pushes them out to remote vCenter servers.
Note: The OVF Transfer Plugin from the VMware marketplace needs to be installed before installing this package. The package can be found here: https://marketplace.vmware.com/vsx/solutions/vmware-realize-orchestrator-ovf-transfer-plug-in
