Kubernetes Clusters: At least two Kubernetes clusters which are part of the same metropolitan area network with a maximum network latency of 10 ms between them.
For a new installation, meet the minimum prerequisites.
Network Connectivity:
Kubernetes: All worker nodes are able to reach Kubernetes API endpoints on both Kubernetes clusters, for example, port 6443, 443 and so on.
To know more about the specific ports for your environment, see the Network table on the Prerequisites page.
External KVDB: An external KVDB etcd setup outside the clusters. To know how to setup an external etcd, see Install KVDB.
Applications Registration: For certain Kubernetes applications, you should create an ApplicationRegistration CR first to facilitate the successful migration of them. Refer to the ApplicationRegistrations page for more information.
