Plan the Mapping of the NSX-V Topology to the NSX Topology

Review the NSX-V topology and decide how to map it to the NSX topology. During the migration, the "Define a Topology" step will prompt you for the mapping.

Specifically, determine how many NSX Edge clusters you need and how Edge Service Gateways (ESGs) and Distributed Logical Routers (DLRs) should map to gateways in NSX. The northbound ESGs without any L4-L7 services should be skipped. These are usually the ESGs peering with northbound routers and are in ECMP path. If you are using VPN on a northbound ESG, migrating to active-standby tier-0 is recommended. In other cases, migrating the ESGs/DLRs to tier-1 is recommended. An ESG and a DLR can be merged in one mapping entry in the mapping file.

An example of a mapping file that maps ESGs to a tier-0 gateway:

[
  {
    "name":"nsxv-to-nsxt-mapping",
    "v_edges_to_policy_gateways_mappings":[
      {
        "v_edges":[
          "edge-1",
          "edge-2"
         ],
         "policy_gateway_name": "tier0-gateway"
         "policy_gateway_path": "/infra/tier-0s/tier0-gateway"
      }
    ]
  }
]
